from bugzilla #105:
"ngircd-16 works great under openbsd4.7/i386, but it segfaults on
openbsd4.7/amd64."
Caused by missing function prototypes and the resulting truncation of
pointer to int.
Lets try to catch these bugs during compilation instead of SIGSEGV.
# Add additional CFLAGS, eventually specified on the command line, but after
# running this configure script. Useful for "-Werror" for example.
+test "$GCC" = "yes" && CFLAGS="$CFLAGS -Werror=implicit-function-declaration"
test -n "$CFLAGS_END" && CFLAGS="$CFLAGS $CFLAGS_END"
