GL_ARB_multitexture on Solaris/Sparc OpenGL

[vincent at cojot.name]

Just something I stumbled on:

In quake3 (linux_glimp.c), there is:
     if ( r_ext_multitexture->value )
     {
       qglMultiTexCoord2fARB = ( PFNGLMULTITEXCOORD2FARBPROC ) dlsym( glw_state.OpenGLLib, "glMultiTexCoord2fARB" );
       qglActiveTextureARB = ( PFNGLACTIVETEXTUREARBPROC ) dlsym( glw_state.OpenGLLib, "glActiveTextureARB" );
       qglClientActiveTextureARB = ( PFNGLCLIENTACTIVETEXTUREARBPROC ) dlsym( glw_state.OpenGLLib, "glClientActiveTextureARB" );

This currently doesn't compile on Solaris since OpenGL on Solaris doesn't 
have PFNGLMULTITEXCOORD2FARBPROC, PFNGLACTIVETEXTUREARBPROC and 
PFNGLCLIENTACTIVETEXTUREARBPROC.

In Quake2 we made it work/compile this way:

                 if ( gl_ext_multitexture->value )
                 {
                         ri.Con_Printf( PRINT_ALL, "...using GL_ARB_multitexture\n" );
                         qglMTexCoord2fSGIS = ( void * ) qwglGetProcAddress( "glMultiTexCoord2fARB" );
                         qglActiveTextureARB = ( void * ) qwglGetProcAddress( "glActiveTextureARB" );
                         qglClientActiveTextureARB = ( void * ) qwglGetProcAddress( "glClientActiveTextureARB" );

I don't think it would be a good idea to 'lose' information by replacing 
'(PFNGLMULTITEXCOORD2FARBPROC)' stuff with '(void *)' in order to make 
this compile on Solaris but what would you recommend that I choose?

1) "#ifdef __sun" some stuff in linux_glimp.c
2) #define PFNGLMULTITEXCOORD2FARBPROC et al for Solaris in qgl.h (ugly).
3) Create a solaris_glimp.c and work from there...

(Note: ioq2 already has some solaris-specific routines so I don't mind 
creating a solaris_glimp.c)

Thanks for reading,

They cannot scare me with their empty spaces
Between stars - on stars where no human race is
I have it in me so much nearer home
To scare myself with my own desert places.       - Robert Frost
