Or, without using DOSKEY, you can just put this little 'trampoline'
batch file somewhere in your existing path. 

---- emacs.bat: ------
@echo off
rem just a little safety check:
if "%DJGPP%"=="" goto DJGPP_MISSING
c:\djgpp\gnu\emacs\bin\emacs %1 %2 %3 %4 %5 %6 %7 %8 %9
goto done

:DJGPP_MISSING
echo "Error: to run DJGPP Emacs, the DJGPP env. variable ought to be set!"

:done
-----------------------

I personally have one whole directory full of such batches, and that's
put in the path. Clever use of this technique can often greatly help
in reducing the path length. Most programs don't actually have to be
put in the path, after all: just cd'ing to their directory and
starting them from there works at least equally well. OTOH, that
directory full of batches will be quite a messy collection of things,
but that doesn't really matter.

And if that's not enough, you can still set up some additional batches
using path changing tools like 'apath.com' to do this

---- djgpp.bat -------
set DJGPP=c:\djgpp\djgpp.env

rem Prepend a dir to the path:
apath c:\djgpp\bin

rem Appending would be 'apath +c:\djgpp\bin'
----------------------

---- dj_end.bat ------
set DJGPP=

rem *Remove* this dir from the path:
apath -c:\djgpp\bin
----------------------

So you'll only have those parts of the path active that you actually
use at the moment.
