[Patch, Fortran] PR 38152: [4.4 Regression] procedure pointers as module variables

[Janus Weil]

Hi all,

here is a patch for PR 38152, which fixes procedure pointers as module
variables. It is a regression in the way that 4.3 aborted gracefully,
stating that procptrs are not implemented, while 4.4 produces a nasty
ICE.

The patch is regression-tested on i686-pc-linux-gnu. Is this ok for
trunk, or should I wait for 4.5?

Thanks to Daniel for reporting this ...

Cheers,
Janus
