[Patch, fortran] PR52846 - [F2008] Support submodules

[Paul Richard Thomas]

Dear All,

Committed as revision 225354.

Compared with the submitted version, I have added another test -
submodule_7.f90. This is a slightly tweaked version of the example in
the F2008 standard. In order to get it to compile, the error produced
by the main program's interface block was suppressed by excluding
module procedures from the error in interface.c. Otherwise, the
compiler complains that module procedures are not module procedures.

Thanks to Damian, Reinhold, Salvatore and FX for help, comments and advice.

I'll get on and sort out the business with private symbols now.

Cheers

Paul

I don’t think, cause you don’t seem to bump the version number, but have you checked on specific cases (like, the mega cp2k example) that the patch indeed does not change existing module files (the ones that do not use submodules)?
