Code Activity

Use Gnulib's `warning' module.

Browse source 
* m4/gnulib-cache.m4: Add `warnings'.

* configure.ac: Use `gl_WARN_ADD' to check whether compiler flags are
  supported.

* libguile/Makefile.am (libguile_la_LIBADD): Add $(LTLIBICONV).
  (libguile_la_LDFLAGS): Add $(INET_NTOP_LIB) $(INET_PTON_LIB).

gl_REPLACE_ARPA_INET_H
dnl The AC_SEARCH_LIBS call is a hack to persuade the Solaris 8 linker to
dnl find inet_ntop.
dnl
dnl It is the responsibility of gl_INET_NTOP's caller to arrange for
dnl -lnsl if it is needed. Normally -lnsl is not needed on Solaris 8,
dnl since inet_ntop is needed only by getaddrinfo, and getaddrinfo
dnl isn't built on Solaris 8.
dnl Most platforms that provide inet_ntop define it in libc.
dnl Solaris 8..10 provide inet_ntop in libnsl instead.
