Jeremy,

I'm getting a ton of warnings when glapi_gentable.c is compiled:

glapi_gentable.c: In function ‘_glapi_create_table_from_handle’:
glapi_gentable.c:52:10: warning: ISO C forbids passing argument 2 of

I think the generator needs to insert some casts to pass the right 
function pointer type rather than void *.
