patch?   What is your change ?   Are you actually doing a "return" or
just an exit here or what was the intention?  A return(0) perhaps?

The problem is not "my compiler" but "the code" wherein there are
for void functions.  That is just wrong on all compilers.  The fact that
this somehow slides past GCC makes me question GCC even more.

Perhaps now is a good time to try some pedantic flags on GCC and find
possibly hidden bugs that may be all over the place and you just
are not seeing them.  Better yet, some test platforms are needed on some
OS's like Solaris, AIX, HPUX, OpenBSD perhaps.

Regardless, getting this gnuTLS code to compile on a commercial UNIX
Solaris is a major incredible pain.
