Getting a different warning now:

glapi_gentable.c: In function ‘_glapi_create_table_from_handle’:
glapi_gentable.c:54:24: warning: ISO C forbids assignment between 
function point

I think you'll need to use a casting function along the lines of this 
from gallium's u_pointer.h:

typedef void (*func_pointer)(void);

static INLINE func_pointer
pointer_to_func( void *p )
{
    union {
       void *p;
       func_pointer f;
    } pf;
    pf.p = p;
    return pf.f;
}
