not a huge number. Implement oscmpswap32 for gccmagic/cmpswap.c create a function pointer like cmpswap called cmpswap32 assigned oscmpswap32 to cmpswap32 in main.c change all sem* bits in a/sysproc.c to use uint32 not long change ed script so it won't do the wrong thing in future. ugly, but I don't see a non-ugly way to do it. ron
