[Users] Mojave|Simfactory|Fortran(thorn): F90 compiler rejecting "_##" in var names

I'm getting an error I've never seen before.  The GNU Fortran compiler (gfortran-mp-4.8)  is tripping over the use  of "_##" in variable names, which are being generated via the build process.  I'm familiar with underscores being an extension, however I've never seen pound signs before in variable names and I can't find any statements online as to these characters being allowed.

Presumably this is an extension that I need to enable -- any suggestions?   I've already got -std=gnu enabled.*

Eclipse > Mojave > Build...

/usr/bin/python simfactory/lib/sim.py build --mdbkey=make -j 8 --verbose bruiser --thornlist /Users/shawley/ThornLists/ThornListBruiser --optionlist /Users/shawley/options.bruiser.mac

IN DIRECTORY: /Users/shawley/Cactus

Error: PARAMETER at (1) is missing an initializer

Two more questions:

1.  What is the simfactory analog of "SILENT=no"?   I see "--verbose" is already enabled, yet I'd like to see exactly what command (& flags) is being used to invoke the Fortran compiler.

2.  Can the warning re. no "include" directory be safely ignored?
