this on the basis that cURL may be using one c-ares version and UnrealIRCd
another c-ares version, something which obviously can lead to failure due
to ABI differences..
Many years have passed since then and cURL is now frequently build with
AsynchDNS support but without the help of c-ares (eg: on Debian). We can
support this configuration without requiring --with-system-cares since
c-ares is not used by cURL and there's no conflict.
- 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).
