suggests for now having -fcx-limited-range as a language-independent flag,
included in -ffast-math for all languages, which switches from the default
of 1 (2 for C99) to 0 (and -ffast-math -fno-cx-limited-range keeping the
default of 1 or 2) with C99 only changing the default from 1 to 2; and in
future adding logarithmic reduction for both 1 and 2.
I concur.
