Great.  I'm adding tests and warnings for FLT_EVAL_METHOD != 0.

C compilers only comply with Annex F of the C standard when
FLT_EVAL_METHOD == 0.

If a compiler tells us they are not complying with the standard
then we have a clue that things will get strange.

If that is the root cause, then their are a few compiler specific
workarounds that sometimes work.
