Try to compile with fewer warnings on irix64's MIPSpro compiler / environment, which apparently believes that: - off_t can be bigger than size_t. - only mean kids assign things they do not subsequently inspect. I don't try to fix the "error" that makes it say: cc-3970 cc: WARNING File = main.c, Line = 1277 conversion from pointer to same-sized integral type (potential portability problem) uintptr_t sig = (uintptr_t)arg; Because really, what can you do about a compiler that claims to be c99 but doesn't understand that void* x = NULL; uintptr_t y = (uintptr_t) x; is safe? svn:r8948
