Bug#889133: gfortran-7: gfortran mod files include full paths, making software bit unreproducible

I've forwarded the patch to the gfortran list, but I'm not sure what you
mean. I know of no code that uses the value in the header, which appears
to be fairly random based on the compile line (either foo.f90, 
./pkg/foo.f90 or /build/pkg/foo.f90 depending on build system).

I imagine just using basename() is simpler and more likely to be
accepted into production quickly (ie gcc-7, gcc-8)

Please could you take this upstream to the fortran and gcc mailing lists? I'd
rather like to see something like

   -fdebug-prefix-map=

which should go upstream.

Bug#889133: gfortran-7: gfortran mod files include full paths, making software bit unreproducible

[Alastair McKinstry]

Package: gfortran-7
Version: 0.7.2-1
Severity: normal
Tags: upstream patch

gfortran creates binary .mod and .smod files. These are compressed files, which 
look like:
(viewed with e.g. zmore /usr/include/cgns.mod ):

GFORTRAN module version '14' created from 
/build/libcgns-XmhIxt/libcgns-3.3.0/src/cgns_f.F90
(() () () () () () () () () () () () () () () () () () () () () () () ()
() () ())

The full path of the compiled fortran file is included, which can break 
reproducible builds.

A trivial patch is included, to strip the path.
