In fact it allows for a case where if the order of command line arguments passed to the compiler if in some way is wrong, the code generated will force the compiler into passing floating point parameters through the integer registers rather than fp registers which is what the --with-float=hard configure time option is doing. Really Fedora should remove this from the configure line as it only confuses people. For the compiler built can you please post back the output is for a simple function that adds 2 float values and pushes it back up. Ramana
