>becomes a problem when calling library functions (e.g. Warp3D) which expect floats in FPU registers...
!!!
You talk about Warp3D 68k that was using registers
but as Warp3D for OS4 got an "interface" it can be called with parameters on the stack as normal C functions , no?
Edit: Just checked Warp3D 68k = it dont use fpu registers when calling functions but cpu registers only
