Eli:

Thanks for the response (as well as the previous response on my post on using
the make utility under NT) on the v2 port of GDB for DJGPP v2.  I have LFN=y
in djgpp.env.  I have not encountered any problems with LFN with my current
configuration.  I understood that this would enable the use of LFN, however
you suggested that I change it to LFN=n.  Was this a typo--or did I
misunderstand something?  In either case, I will try it.

I also looked at GDB 4.17 from the GNU site to see if DJGPP was supported.  It
appears as though there is some support for DJGPP (the configure script
detects i386-pc-msdosdjgpp as a host), however the configure script eventually
dies when a symbolic link is attempted.

I don't have a great amount of time (as I am sure many don't) to devote to
working on a port for DJGPP v2.  To do so would be a side trip from my current
project.  However, I would like to contribute to the great work that many are
doing to support this incredible environment, and I will consider doing so.

To Mr. Delorie:

I would like to thank you for all of your work in providing such a great
development environment.

Regards
Jon
