[Fortran, patch] Fix for PR fortran/26054: Gratuitous warning about Fortran 2003 features.

I agree with the submitter of this bug report that we should
not warn *by default* about the Fortran 2003 features we support.
There are other extensions to the Fortran 95 standard that won't
ever be in any standard that we silently support, like REAL*8.
This is my proposal to deal with this bug report:

* fortran/options.c: Do not warn for Fortran 2003 features
by default.
* testsuite/gfortran.dg/enum_8.f90: Remove check for warning.
* testsuite/gfortran.dg/iomsg_1.f90: Ditto.

Tested on x86_64-unknown-linux-gnu against the head.
OK for trunk and the 4.1 branch ?
