[Bug fortran/39030] New: Support -fexcess-precision={standard,fast} also for Fortran

[burnus at gcc dot gnu dot org]

>From http://gcc.gnu.org/ml/fortran/2009-01/msg00332.html:

The C99 patch (for GCC 4.5),
http://gcc.gnu.org/ml/gcc-patches/2008-11/msg00105.html, fixes the excess
precision problem of the infamous PR 323 (yes, that old). For C99 there exists
a new option -fexcess-precision={standard,fast} which needs front end support.
-- PR 323 is especially about the x87 co-processor rounding, which is not IEEE
conform; work around is -ffloat-store or SSE.

The patch announcement came with "Fixes bug 323 for C (other languages would
need their own front-end work to implement suitable predictable semantics under
the same command-line option in order to complete fixing the bug)."
