Re: don't use AC_FUNC_MMAP, use AC_CHECK_FUNCS(mmap) instead.

AC_CHECK_FUNCS(mmap) issues this:
checking for mmap... yes

This is what I will using now for all the GNOME packages, there are several packages affected, so far I know of:
- libgtop
- gtk+
- libgnomeprint
- libgsf

I think it just tries to link against the system library and it succeeds, so mmap() is considered to be available. Fine with me.

Using the macro AC_FUNC_MMAP, the test fails and mmap() will not be available.

BTW, it looks like this in configure.ac:
case "$host" in
  *cygwin*)
    AC_CHECK_FUNCS(mmap)
    ;;
  *)
    AC_FUNC_MMAP
    ;;
esac
