[Gm2] Request for optional file endings

[jgoyo]

Greetings:

Could you please add options to the compiler to accept different file monikers 
(so that we
may
compile existing code with different monikers)?  Rather than def/mod, the ULM 
compiler
demands d/m2
and mocka demands  d/mi (or somesuch).  At present, I created soft links but 
that is a
poor solution.

I offer the following suggestion:  -Wdef=defend  -Wmod=modend
The default would be def/mod.

Thank you.

Sincerely,
john
