[Patch, fortran] PR25099 - elemental subroutine argument conformance checking

[THOMAS Paul Richard 169137]

Dominique,

I have reconstructed the conformance checking patch. Here it is:

:ADDPATCH fortran:

The attached patch fixes PR25099 by implementing conformance checking
of the actual arguments of elemental subroutines.

The patch is trivial and the testcase is based on that in the PR, with
the addition of checks on operator assignments. Assumed_size_refs_1.f90
need correcting for one non-conforming subroutine call.

I have added the corrected version of elemental_subroutine_3.f90 but
have not included it in the ChageLog entry, since it is part of the
previous patch.

Regtested on Cygwin_NT/PIV - OK for trunk and 4.1?

Paul
