GCC should not put extraneous differences into files that would otherwise be identical. If you upgrade from gcc-1.xx to gcc-1.yy and run a regression test, only the files whose assembler code actually changes should show up as different. This is a major botch in "coff", where they put a timestamp in the object files, and you have to take special precautions to try to compare two versions of object code, e.g. to see if a compiler fix has changed anything.
