Hello,
This one is a translated demo from msdn https://docs.microsoft.com/en-us/windows/win32/opengl/the-program-ported-to-win32.
I have let c++ (/FA) do the math labor.

There is some modifies of the original:

bSetupPixelFormat PROC FRAME hdc:HDC
Local pfd:PIXELFORMATDESCRIPTOR,pixelformat:DWORD
invoke memset,addr pfd,0,sizeof pfd ;init of structure for good colors

invoke Sleep,10 ;Slow a little rotations

latitude GLdouble 0       ;instead of GLfloat to be conform with proto
longitude GLdouble 0
latinc GLdouble 0
longinc GLdouble 0

Fa is a musical note to play with CL

This one is the same code as upper except he use  basic macros for real manipulations.
All macros had been verify by "C language /FA".
The macros works with DWORD,QWORD,REAL4,REAL8
That is enough to use the crt math fonctions here https://docs.microsoft.com/en-us/cpp/c-runtime-library/floating-point-support?view=msvc-160 without too many trouble.
Here the list.
