NeHe Lesson 3 works (crashes at close); Lesson 8 does not work - fixed some bugs in wgl.c and disable asm proxy functions for the moment because they crash svn path=/trunk/; revision=8152

/* On a x86 we call the ICD functions in a special-way:
|
|
*
|
|
* For every glXXX function we export a glXXX entry-point which loads the
|
|
* matching "real" function pointer from the NtCurrentTeb()->glDispatchTable
|
|
* for gl functions in teblist.h and for others it gets the pointer from
|
|
* NtCurrentTeb()->glTable and jmps to the address, leaving the stack alone and
|
|
* letting the "real" function return for us.
|
|
* Royce has implemented this in NASM =D
|
|
*
|
|
* On other machines we use C to forward the calls (slow...)
