Re: [Bug fortran/52846] [F2008] Support submodules - part 3/3

[Paul Richard Thomas <paul.richard.thomas@gmail.com>]

Dear Mikael,

It had crossed my mind also that a .mod and a .smod file could be
written. Normally, the .smod files are produced by the submodules
themselves, so that their descendants can pick up the symbols that
they generate. There is no reason at all why this could not be
implemented; early on in the development I did just this, although I
think that it would now be easier to modify this patch.

One huge advantage of proceeding in this way is that any resulting
library can be distributed with the .mod file alone so that the
private entities are never exposed. The penalty is that a second file
is output.

With best regards

Paul
