[Patch, Fortran, F03] PR52909: Procedure pointers not private to modules

[Janus Weil <janus at gcc dot gnu dot org>]

Hi all,

here is a simple patch for a problem recently reported by Andrew
Benson: Procedure pointers inside a module don't receive the proper
name mangling, which can lead to name collisions (as the test case
demonstrates).

The patch fixes this and regtests cleanly on x86_64-unknown-linux-gnu.
I am aware that it will break the ABI, but only for programs involving
procedure pointers (which still is a 'relatively' new feature,
supported since gfortran 4.4). So, ok for trunk?

Btw, speaking of ABI breaking: What are the chances of the array
descriptor update and ABI cleanup happening for the 4.8 release? I
know such an ABI breaking has been planned for some time, but I
haven't followed the gfortran mailing list in detail during the last
weeks and months, so I'm not sure what the current status is.

Cheers,
Janus
