Configure doesn't find struct addrinfo (because it's in a __USE_POSIX
block) so it looks like we use our own version, but, when we're actually
then compiling getaddrinfo.c, there's a redefinition error because this
time struct addrinfo is found (because _GNU_SOURCE forces __USE_POSIX).

It looks like commenting it out of linux.h and adding it to template/linux
works for the main build, it compiles and links fine both with and without
--std=c89 and the latter also passes regression.  I didn't try to build
plperl however.
