I tried the attached change.  It results in the correct configure
results.  However, the test still fails.  So, probably the isfinite
and isnan defines in libgfortran.h need checking.  Don't have time
to look at this until week after next.

Regard write_float, it looks as if output_float will be called without
any finite or nan checks for B, O and Z formats.
