[AD] [BUG] ccolconv.c void * arith.

[Thomas Fjellstrom <tfjellstrom@xxxxxxxxxx>]

Someone on #allegro was toying with making the MSVC build not dependant on asm 
and hes hit a road block:

<FrozenSpoon> void *src;   src += 4;     = error: void * is unknown size :/

all throughout ccolconv.c it does stuff similar to that, arith on a void 
pointer.

Now GCC will take it (why?) but he says his MSVC will not.
