* automake-am11-am12:
autogen.sh: detect automake version format a.b.c and a.b
configure.ng: don't require GIT tree to detect version string
Include .mailmap file in distribution archives
Include all build-system files into distribution archives
Change build system to support new and old GNU automake
Starting with GNU automake 1.12, the "de-ANSI-fication support" has been
removed, which ngIRCd used to enable building itself on very old systems.
Now the problem is, that using automake >= 1.12 isn't working because of
the now unsupported M4 macros. Therefore the solution that this patch
implements is to dynamically generate the automake input files with our
own ./autogen.sh script:
configure.ng => configure.in
Makefile.ng => Makefile.am
This is quite an ugly approach, but it works and enables us to:
1. use current automake >= 1.12 for development and "private builds",
2. still build distribution archives using automake 1.11.x that have
"de-ANSI-fication support" enabled in the generated Makefile's.
And if you are using Makefile's generated with a automake version newer
than 1.11.x (without "de-ANSI-fication support"), the ./configure script
warns you not to use this generated build system to generate distribution
archives.
Drawback of this patch: you MUST use our autogen.sh script, you can't call
the autoconf/automake commands directly any more; but autoreconf should
still work ...
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.
when building with debugging enabled, but without ipv6 support,
ngircd dumped core when loading a config file that specified an ipv6
listen address.
ngircd: ng_ipaddr.c:45: ng_ipaddr_init: Assertion `sizeof(*addr) >=
res0->ai_addrlen' failed.
Test for sockaddr_in.sin_len and initialize it to the correct value
which some systems (notably Mac OS X) require.
Note: this code path is only relevant when not using getaddrinfo().
this also obsoletes ListenIPv4 and ListenIPv6 options.
If Listen is unset, it is treated as Listen="::,0.0.0.0".
Note: ListenIPv4 and ListenIPv6 options are still recognized,
but ngircd will print a warning if they are used in the config file.
Also, some plattforms require that ai_socktype
is set in the getaddrinfo() hints structure.
all references to struct sockaddr/in_addr have been
removed from src/ngircd.
libngipaddr (in src/ipaddr/) hides all the gory details.
See src/ipaddr/ng_ipaddr.h for API description.
