glapi_x86.S is the trouble maker, it explicity generates calls to
_glapi_Dispatch.
A little snippet from the output from the preprocessor for this file
looks like this
.balign 16; .globl mglNewList ; .type mglNewList, function;
mglNewList: movl _glapi_Dispatch,%eax ; testl %eax,%eax ; je 1f ; jmp *4
* 0(%eax) ; 1: call _x86_get_dispatch ; jmp *4 * 0(%eax)
You'll note the mention of _glapi_Dispatch, It is glapi_x86.S that I
modified to make it output _mglapi_Dispatch instead.

It's suppsed to be _mglapi_Dispatch in mangled mode.
Maybe you can run 'nm' on the .o files to see which one is getting
_glap_Dispatch.
