These should be mostly harmless. The task of ANSI-fying the source code
and minimising build warnings is a long and on-going one.

It is of interest. All platforms are :-)
On FreeBSD/i386 5.1 I get warnings building libGL.so, but they are not
fatal. I haven't tried on 5.2 yet.
I think the patch below should fix this. It eliminates the warnings for
my 5.1 build.
BTW, this is an issue for libGL but not most other libraries because
libGL is built with the -Bsymbolic option.

The gcc version should get auto-detected, and HasGcc2 gets set if HasGcc3
is set:
/*
* GNU Compiler stuff
*/
#ifndef HasGcc3
# define HasGcc3 NO
#endif
#ifndef HasGcc2
# define HasGcc2 HasGcc3
#endif
#ifndef HasGcc
# define HasGcc HasGcc2
#endif
You can confirm the gcc version auto-detection by running
'make -f xmakefile VerifyOS' from the xc directory.
