Description nvwarr 2023-03-10 15:35:33 UTC 
Description of problem:

redhat-rpm-config injects flags to gfortran, which are appropriate for the C/C++ compiler and/or preprocessor but not for Fortran.

Version-Release number of selected component (if applicable):

redhat-rpm-config-252-1.fc38.noarch

How reproducible:

always

Steps to Reproduce:
1. build an rpm containing Fortran code

Actual results:

three warnings are generated, which are not generated outside of rpmbuild

f951: Warning: ‘-Werror=’ argument ‘-Werror=format-security’ is not valid for Fortran
f951: Warning: -D_FORTIFY_SOURCE not defined
annobin: test.f: Warning: -D_GLIBCXX_ASSERTIONS not defined

Expected results:

should not pass -Werror=format-security -Wp,-U_FORTIFY_SOURCE,-D_FORTIFY_SOURCE=3 -Wp,-D_GLIBCXX_ASSERTIONS to gfortran.

Additional info:

this has actually been around for a while, but has only just crossed my annoyance threshold:)

Some discussion in PR 254. I'm working on a different approach.
