This fixes the following warning messages of gcc 4.5.3 on Cygwin when
building with debug code enabled:
ng_ipaddr.c: In function ‘ng_ipaddr_init’:
ng_ipaddr.c:52:2: warning: comparison between signed and
unsigned integer expressions
ng_ipaddr.c:53:20: warning: comparison between signed and
unsigned integer expressions
resolve.c: In function ‘ForwardLookup’:
resolve.c:271:3: warning: comparison between signed and
unsigned integer expressions
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.
