I am concerned, however, with the portability of the library. I mean, is the calling convention for both void func(vect v); void func(float x, float y); the same on x86? On x86-64? On Windows? On Linux? I guess it would be a lot faster to pass the arguments on the stack than alloca'ting, copying to the new area and then copying from the area to the stack, but I don't want to sacrifice the portability.
