[Bug fortran/13702] New: [gfortran] When preprocessing Fortran files (.F, .F90 and .F95) cpp should emit line numbers.

[Bug fortran/13702] New: [gfortran] When preprocessing Fortran files (.F, .F90 and .F95) cpp should emit line numbers.

[toon at moene dot indiv dot nluug dot nl]

Currently, when preprocessing Fortran files, gfortran calls cpp with the -P
option, which prevents it to emit line number information.

The reason for this is that, at the moment, the Fortran front end cannot process
these directives.

However, for debugging purposes it's paramount that this infomation is emitted
by cpp and interpreted by the Fortran front end; without it, line numbers in
debugging records will refer to the lines in the preprocessed source, not the
original.
