Updates to SGI GLU code to get it to compile clean with the Open Watcom compiler.
Most of the changes were to get rid of warnings, but many of the warnings could
not be removed in the code so I also added #pragma's to disable the warnings.
Someone really should clean up this code, but I didn't want to mess with it
that much (and potentially break it).
Add GLAPIENTRY to typedef for callback functions (used by tessellator).
This is important now that we're using __stdcall instead of the (default)
__cdecl on WIN32. This gets apps using the tessellator working again
on Windows.
. Updated GL/gl.h with GLCALLACKP and GLAPIENTRYP macros for compatibility
with the IBM VisualAge C++ compiler. Eventually some more code will be
needed in the headers to enable the reversal of (__stdcall*) to (*__stdcall)
for the IBM compilers, however we currently build using our own header files
that already handle this.
. Changed instances of (GLCALLBACK*) to GLCALLBACKP for compatibility
with the IBM VisualAge C++ compiler in src-glu.
. Misc cleanups for warnings generated with Watcom C++ in src-glu. Compiles
with 0 warnings now.
. tess_hash.c: line 244 - Why is this function stubbed out? I removed the
code with a #if 0 to avoid a compiler warning, but it looks dangerous.
