Bug #: 53481 Summary: Allow for gfortran (f951) specs option Classification: Unclassified Product: gcc Version: 4.8.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: fortran AssignedTo: unassig...@gcc.gnu.org ReportedBy: bur...@gcc.gnu.org Cf. http://gcc.gnu.org/ml/fortran/2012-05/msg00135.html As far as I know there is no spec f951, and there is no way to use the specs file to change the options passed to the Fortran compiler. The Fortran frontend doesn't use any named specs that you can change; the specs are compiled into the driver program directly, from the source file gcc/fortran/lang-specs.h. Seemingly, "cc1plus" supports spec files, cf. gcc -dumpspecs
