You most definitely do not need to make a copy of errno. As proof, we don't make copies of it anywhere in APR, and it works on every platform we have tried. While errno is not a simple variable, compilers are smart enough to treat it as if it is a simple variable, so just 'return errno' works everywhere. Ryan
