- Fix bundled TRE compilation error on OpenBSD with pkg-config-0.21
  where pkg-config can't find 'tre.pc'. Reported by CuleX. (#3982)
  Also properly escape the sed expression used in the pkg-config call.

- Fix invalid use of 'wc -l' when detecting the AsynchDNS feature of
  libcurl which breaks compilation on FreeBSD; instead use 'grep
  -q'. Reported by Jobe (#3981), solution proposed by satmd.

- Fix missing #include <stdint.h>. Fixes compile error on OpenBSD
  reported by CuleX (#3977).

- Fixed bug with curl not finding libcares, reported by katslaw.
- Added workaround for 'curl-config' depending on 'bc'.

- Prepend a `0' to the begining of --with-permission, working around a Mac OS X bug and hiding the fact that chmod()'s params are octal from users. (#3189)

- Install ircdcron scripts. (#2620)
- Autogenerate ircdcron/ircd.cron based on ./configure settings.

- Upgrade to tre-0.8.0, adding hack similar to the one for c-ares to ensure that the bundled tre is compiled against even when a system libtre is installed. (#3916)

- Remove extras/c-ares before each time c-ares is compiled.

- Force compilation with bundled c-ares to statically link using more sed hackery in configure.ac.

- Upgraded c-ares to 1.7.3. API seems compatible with c-ares-1.6.3. (#3932)

- Fix a few compiler warnings with some double-casting and another const. (#3939)

- Fix the detection for curl-without-c-ares a little (#0003940). ** fun.. autoconf 2.61**

- Now define _SOLARIS, USE_LIBCURL, and ZIP_LINKS in setup.h instead of the Makefiles. This means better automatic rebuilds if the latter settings change.

- Support compiling with a bundled c-ares again, the hacky way. (#3931)

- Remove extraneous `I' from configure.ac, run ./autogen.sh. (#3930)

- Move configure.ac to the project's root.
- Separate m4 macros into *.m4 files (it is much easier to run aclocal now).
- Remove unused DOMAINNAME macro and --with-hostname= options as the DOMAINNAME macro isn't used anywheres and its use shouldn't be encouraged.
- autogen.sh to bootstrap the buildsystem. We now maintain setup.h with autoheader.
- --disable-blah now does the opposite of --enable-blah. The same for --with-blah and --without-blah. (This makes Gentoo users happier).

- Rename configure.in to configure.ac and modernize AC_INIT.

- Remove the Compile as hub/leaf'' concept as I'm quite sure this doesn't actually do anything (#0003891)

- Updated pkg-config m4 macro (now 0.23) for configure, patch from ohnobinki (#0003889).

- Another c-ares fix for Solaris 10, this time it had to do with
  PATH_SEPARATOR, the exact error was: error: PATH_SEPARATOR not set.
  Reported by j0inty, patch provided by ohnobinki (#0003887).

- Fix for --with-system-cares, reported and patch provided by ohnobinki (#0003890).

- Reverted the revert and updated one line to fix the fix.

- Patch from above is (temp.) reverted, Unreal wouldn't compile without curl.

- Added patch from ohnobinki (#0003888), only slightly edited, which improves
  curl detection, added checks to see if curl actually works (print out a
  clear curl error during configure, instead of getting an error during
  'make'), and we now error when using --enable-libcurl without
  --with-system-cares if the system curl depends on c-ares. This is because
  this can cause ABI incompatability between curl's c-ares and our c-ares,
  which leads to odd issues such as:
  Could not resolve host: www.example.net (Successful completion)
  And possibly other weird issues, perhaps even crashes.

- Added support for "chained" extbans. Put simply this allows extban combinations
  such as ~q:~c:#test to only silence users on #test, for example. This feature
  is enabled by default, but can be disabled during ./Config -advanced. Module
  support for this feature must note the following:
  - For is_ok function, the extban can either assign extban_is_ok_nuh_extban, which
    will deal checking a chained extban (including checking for restricted extbans),
    or it can call that function from its own is_ok routine. For the latter case,
    remember to pass only the mask part of your ban format (ie, don't just pass para as
    otherwise it'll just call your is_ok again).
  - For conv_param function, the extban can either assign extban_conv_param_nuh_or_extban,
    which will automatically call conv_param for a chained extban, or pretty up a n!u@h mask.
  - For is_banned, the extban should call ban_check_mask with the mask part of the parameter.
    This will automatically call is_banned for a stacked extban, or match against a n!u@h. n!u@h
    is checked against the current user (ie, with the info in the globals ban_ip, etc), so things
    can get weird if you call this outside a normal ban check.
  Modules must keep in mind that chained extban support is not available (and neither are the three
  functions above) if DISABLE_STACKED_EXTBANS is #defined (this is controled by Config). Modules will
  not compile/load if they try to use them anyway.
  This change should not break extban modules, and should need some more extensive testing.
- Misc fix for disabling extban chains, should've done stuff in our autoconf
  stuff instead of hacking configure directly :P .

- Applied another patch from ohnobinki which adds --with-system-cares
  (#0003847).

- Added ./configure option called --with-system-tre by which you can specify
  a path to the TRE library (instead of using the TRE we ship with Unreal).
  Patch provided by ohnobinki (#0003842).

- Print out an error if a user uses standard ./configure stuff instead of
  ./Config. Won't catch all cases, but will definitely catch most problems.

- Fixed compile issue on Solaris regarding c-ares (-lrt), reported and
  test shell provided by fraggeln (#0003854).
- Improved automatic SSL detection on Solaris (/usr/sfw), reported by
  fraggeln (also #0003854).

- Fix for compile problem on FreeBSD (and possibly other OS's):
  - When pkg-config is present but does not recognize --static, use
    default c-ares library options.
  - Set default c-ares library options to -lcares on FreeBSD and others.
    Set to -lcares -lrt on Linux (previously was -lcares -lrt for all).
  Thanks to goldenwolf for the bugreport (#0003803) and providing a test-
  shell to trace this issue down.

- Win32 makefile: removed /MAPINFO:LINES, since visual studio 2005 and up
  don't support this and will fail to compile UnrealIRCd. This fixes #3680,
  reported by therock247uk.
- Upgraded c-ares to 1.6.0 (also now using pkg-config).
  If you get a "undefined reference to `clock_gettime'" error, then you
  might consider installing 'pkg-config' on your system, and then simply
  re-run
  ./Config and make, should fix things.
__TODO__: win32 c-ares upgrade to 1.6.0 (and copy & fix header files).
__TODO__: testing! testing! i'd like to be sure this c-ares is stable!

- configure script is now generated by autoconf 2.61 (was: 2.59), hopefully
  that won't cause any issues, perhaps it even helps to fix some bugs...

- Upgraded c-ares to 1.5.1, thanks to aegis for the partial patch (#0003671).
  This also fixed a curl compile/run issue, reported by static-x (#0003545).

+- Updated c-ares to version 1.4.0

- c-ares resolver: upgrade to 1.3.2.

- c-ares resolver: upgrade from 1.3.0 to 1.3.1. This mainly fixes compile problems,
  including one reported by frigola on an old Sun Cobalt RAQ3.
  It will probably also fix an issue with the just released curl 7.15.4, if compiling
  with remote includes.
  TODO: Update win32 (not urgent)

- Fixed problem if c-ares library is already installed system-wide, reported by Trystan.

2>/dev/null plz

try this ~

- c-ares (currently, a forked off version) enhancements:
  - '/quote dns i' now shows the nameserver settings (which is taken from /etc/resolv.conf
    on *NIX, and from the registry on Windows)
  - We no longer depend on a C++ compiler (was useless c-ares dependency caused by libtool)
  - '/REHASH -dns' now rereads the resolver data from resolv.conf/registry, no IRCd restart
    needed anymore. It's currently kinda experimental however, but I *think* it will work ok.
  Unfortunately the above features required some ugly hacks if curl was enabled, so if you
  use curl (Remote includes), feel free to test on your OS (Linux, but especially FreeBSD
  and the other *NIXes) to see if things still compile (make clean; ./Config && make).

- Updated autoconf/configure.in to make newer autoconf's work (developers only), reported
  and patch provided by Xuefer (#0002798). Also rebuilt ./configure from configure.in with
  autoconf 2.59 from my own machine.

- Made the "strict aliasing"-warning-disabler use $CC instead of gcc.
- Made ./Config better react to errors (no longer print a "everything is a big success"
  kind of message when in fact everything went wrong).
- Made ./Config (configure) exit on openssl or zlib not found errors, instead of
  silently continueing and then causing trouble later on. Also now printing _a bit_
  more helpful error message.

- Removed all old resolver code and switched over to c-ares (+our caching routines).
  This should get rid of some annoying untracable (and usually rare) crashbugs in the
  old resolver. Besides that, it makes things look more clean and understandable.
  This should be the fix for the following bugids (all the same issue): #2499, #2551, #2558,
  #2559, #2603, #2642, #2502, #2501, #2618, #2616.
  Feedback and testing is very much welcomed (syzop@unrealircd.com).

blah.. that didn't work, this does. [seperate case/esac]

- Added -Wno-pointer-sign to get rid of those stupid warnings that are enabled by default
  even without -Wall (!?) on GCC4.

- IPv6: Added configure check for in6addr_any to fix Fedora Core 4 compile problem,
  reported by wheatie80 (#2594).

- Added -fno-strict-aliasing
..more on that later..

Imported TRE 0.7.2 for *nix

Rewrote some of the previous change to deal with some strange issues

Made ./Config better handle command line arguments, Removed NAZIISH_CHBAN_HANDLING as it didn't do anything, Added -advanced flag to ./Config to configure advanced options

Fixed a +u problem and updated to TRE 0.7.0

Made Unreal create the tmp/ dir at startup, rather than configure

Imported TRE 0.6.8 for *nix

Configure checks for inet_ntop/pton

Updated to TRE 0.6.7

- Force a TRE recompile if ./Config is re-run, due to timestamp fun if you were
  upgrading to CVS every time TRE was not recompiled even if you did make clean.
