Details:
I have been compiling Freeciv with the gcc 3.3.5 (propolice) that comes with
OpenBSD. This version does not support __attribute__((warn_unused_result)),
so gcc emits a warning at every instance of warn_unused_result. I see about
four warnings per .c file.
Documentation says that gcc 3.4 has warn_unused_result
<http://gcc.gnu.org/onlinedocs/gcc-3.4.0/gcc/Function-Attributes.html> but
gcc 3.3 lacks it
<http://gcc.gnu.org/onlinedocs/gcc-3.3.6/gcc/Function-Attributes.html>.
This patch to utility/support.h and utility/mem.h checks for gcc 3.4 and
defines and uses fc__warn_unused_result.
This patch is for S2_2.
