I hope you can help.  As I am sure you have seen many times before, I am
a new user trying to get djgpp going and having trouble with the
compiler not finding iostream.h.  All the gory details are below.

I subsequently tried to force my program to find iostream.h by doing 
include "c:\djgpp\lang\cxx\iostream.h"
in the header of the source code.  The compiler then found iostream.h,
but got an error trying to find streambu.h, which I suspect could be a
DOS 8+3 naming problem.  Anyway, it was clear to me from this that my
iostream.h file is there.  Clearly there has to be a better solution
that "hard-coding" all the exact locations of the libraries in every
program, though.

I also tried to use the FAQ and searchable mail archives (great
resource, by the way!) , finding some very relevant tips.  Here are my
responses to questions that were posed in one such mailing.
(1)  Did you put all your djgpp stuff in the C:\DJGPP\ directory?
-->Yes
(2)  Have you have all the files in the readme.1st file?  Iostream
library is in a different zip file from which G++ is included.
-->Yes, I have c:\djgpp\lang\cxx\iostream.h
(3)  Have you unziped all the files in the djgpp directory and with the
-d switch if you are using pkunzip?  Or have you mkdir the directories
your self?
--> I used winzip95 which created the directory structure for me
(4)  Did you modify your djgpp.env file?  If yes, posted here and let
me see.
-->No I didn't modify it, but I've attached it below.

I also tried playing with the capitalization of iostream.h (versus
IOSTREAM.H) in the source code to no avail.  A desparation move, which
prompted me to write to you.

Thanks!  I really appreciate that you provide this kind assistance to
struggling amateurs like me!
