Bug 6938

I tried to build the CVS version of Mesa with function name mangling
(added -DUSE_MGL_NAMESPACE to the defines in sunos5-gcc) on Solaris 9
with the gcc 3.4.2 of sunfreeware and it breaks with errors.

GCC version:
egger@blade02 configs$ gcc -v
Reading specs from /usr/local/lib/gcc/sparc-sun-solaris2.9/3.4.2/specs
Configured with: ../configure --with-as=/usr/ccs/bin/as
--with-ld=/usr/ccs/bin/ld --disable-nls --disable-libgcj --enable-languages=c,c+
: (reconfigured) ../configure --with-as=/usr/ccs/bin/as
--with-ld=/usr/ccs/bin/ld --disable-nls --disable-libgcj --enable-languages=c,c++
Thread model: posix
gcc version 3.4.2

The link errors:
