- Add generated sample-ngircd.conf to new .gitignore file, - refactor Makefile.am to generate sample-ngircd.conf on "make all", to clean it up on "make clean", and to install it to the correct place. - Make sure path names in sample-ngircd.conf are separated by "/".

If a hostname resolves to more than one IP address (round-robin DNS, IPv4 and IPv6) and an attempt to connect to the first address fails, ngIRCd should try to connect to the 2nd address, 3rd address etc. But because of a wrong variable used in the call to New_Server(), the wrong server structure has been used in further connection attemps which possibly lead to connection attempts to already connected servers.

This is required for backwards compatibility when installing the -full or -full-dbg package variant: PAM is enabled now but no configuration present, so all login attempts would be denied ... Creating /etc/pam.d/ngircd including "auth required pam_permit.so" restores the old behaviour of allowing all connections.

disable pam_fail_delay() only is available starting with Mac OS X 10.6; but we use the 10.5 SDK for campatibility, so don't use this function at all when building using Xcode.

This is required for universal 32 bit and 64 bit builds: now code for ppc, i386, and x86_64 is generated (which requires 10.5 or newer).

- handle version numbers generated by "git describe" - detect gcc compiler version correctly when "-std=xxx" is used

Now the ngIRCd release/version number is deduced from the "current" annotated GIT tag; see "git describe --help" for details. This is the same scheme the Linux kernel uses and gives much more details version numbers for interim releases and inofficial source archives generated using "make dist". Please note: the version number is only updated it the autogen.sh script is run; so after pulling in and pushing out new commits, you should run ./autogen.sh!

This allows to compile ngIRCd using a pre-ANSI K&R C compiler again: all source files are automatically converted by the included ansi2knr program (of GNU automake/autoconf) before compiling them with the K&R C compiler, but a few coding standards must be met. Tested on Apple A/UX 3.x. Regression testing on Linux and Mac OS X.

This is required for enabling ansi2knr on systems that don't have an ANSI C compiler installed (e.g. on A/UX with Apple standard C compiler).

The PARAMS() macro is only needed for function prototypes; don't use it for the actual implementations.
