Type this at the prompt before running any DJGPP-compiled program
(including gcc) that you want to use long filenames with: 

set lfn=y

Conversely, set lfn=n will turn off long filenames.

You are correct in assuming that your programs won't need any special
modifications to use long filenames, and that DJGPP is a port of the UNIX
gcc compiler.
