In general, the answer is "somewhere between easy and impossible" :)

As you are talking about FORTRAN and you want to use MMS, ignore the 
un*x build and generate description files with MMS/GENERATE, then tweak 
if needed.

I've used this (with a custom written parser to detect and cope with 
some unconventional include files) to automatically generate MMS for a 
code base approximately 10 times the size you mention further 
down-thread, written in ANSI COBOL.  Of the 100K or so source modules, 
only about ten or twenty of the generated MMS description files needed 
to be tweaked to get it to work.
