[Patch, fortran, RFC] PR 40958 Reduce size of module files

[Salvatore Filippone]

Hi Janne,

I am very happy to see someone working on this. I am setting up a test
environment; my PSBLAS and MLD2P4 libraries produce multi-megabyte mod
files, and the compile time is really awful.
I'll be back with measurements asap
