This consists of two largely separate issues:

1) DOS support on XP is subtly broken in many "interesting" ways, for which
   you need an updated version of DJGPP to take care of.  Search this
   newsgroup and you'll find lots of references to that.

2) Setting up DJGPP as non-admin on an NT-style box means you have to 
   avoid any changes to the master environment.  That still leaves two
   choices:

   * Change the individiual user's private environment variables instead.  
     On XP, you would to to Control Panel --> System --> Extended and
     select "Environment".  Add the environment variables in the upper
     pane, which shows the "user environment".  The drawback: the change
     is global to all programs run by that user --- some may not like the
     PATH change, esp. other compilers installed on the same machine will
     become confused.

   * Put the two relevant 'set' commands into a batch file, let's call it
     "setvars.bat", and create a desktop link with the commandline

	%SystemRoot%\system32\cmd.exe /k c:\djgpp\setvars.bat

     Whenever you want to work with DJGPP, open this link and it'll create
     a command line shell set up for it.  It's a good idea to give this
     link a keyboard shortcut (I usually choose Alt+Shift+D).  If you use
     more than one compiler toolchain, this method is the only somewhat
     workable one.  You'll have to create one such link for each of them.
     The drawback is that DJGPP-compiled programs executed from outside that
     shell will not see the DJGPP environment variable, which they may need
     for proper operation.

The best solution may actually be a combination of the two: put
"DJGPP=c:\djgpp\djgpp.env" in the user's environment settings, and
leave the PATH change to the batch file.

Or have a word with that admin to allow DJGPP=... in the global
environment.
