* But if we're using X86-optimized dispatch (X86/glapi_x86.S) then
* each of the entrypoints will be prefixed with _glapi_fallback_*
* and will be called by the glapi_x86.S code when we're in thread-
* safe mode.
*
* Eventually this file may be replaced by automatically generated
* code from an API spec file.
*
* NOTE: This file should _not_ be used when compiling Mesa for a DRI-
* based device driver.
