Subject: Re: -m486

I've just recently downloaded and intstalled the djgpp executables 
from OAK.OAKLAND.EDU. There ARE documentation files included with 
most or all of the modules however, I haven't seen a 'definitive' set 
of User Guides or Reference Manuals (perhaps in PS format?) which contain 
information about the command line switches of the various 
components as well as the interactions and expectations of the 
components.

Does such exist in either binary or printed form?
Short of downloading the Unix gcc files and rooting around in them, 
I'm at a loss (except for the FAQ which I haven't seen yet).
Help? Pointers?

Thanks for any newbie type help.                      ...edn
