Me too. I assume this means we needn't worry about the x86 rounding glitches,
except perhaps to document them. So we can fold constant expressions involving
floating point without worrying abouth these glitches.

For sanity's sake, we should generate Emacs tarballs on a platform other than
GNU/Linux x86, which is a pretty easy bit of advice to follow as hardly anybody
runs that platform for software development nowadays.
