--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
But it is the later fpre-include.

#define TARGET_F951_OPTIONS "%{!nostdinc:\
  %:fortran-preinclude-file(-fpre-include= math-vector-fortran.h finclude%s/)}"


I wonder if find_fortran_preinclude_file could be extended to say only include
it with -ffast-math enabled (or the other options needed for -ffast-math).

Since the driver still does processing of the options.
