Thanks for your fixes. Yes, the goal was portability rather than saving a few instructions. A high-performance implementation of totalorder would need help from the compiler anyway, just as signbit gets help from __builtin_signbit with GCC.
The win for GNU sort, once I get around to fixing totalorder's -lm dependency, is that it can call totalorderl instead of doing what it does now, which is to call sprintf twice and then strcmp.
