I obviously don't know anything about the code of your installer, so
my advice shouldn't be taken literally.

If this test is done before DJGPP is set, use the directory name to
check the acessibility of DJGPP.ENV.  If DJGPP.ENV doesn't yet exist
(because you do this test before unzipping djdev), create it
temporarily using the installation directory name chosen by the user
and then test.

The point is, if %DJDIR%/DJGPP.ENV *can* be accessed, the installation
is probably okay, except that if the user wants the installation to
work in plain DOS mode and the numeric tails weren't turned off (you
can test for this latter part by truncating the file name to 8+3 and
then trying to access the truncated name: if numeric tails are ON, the
access will fail).  I agree with DJ that a warning about plain DOS
mode should be issued if numeric tails are ON and the user installs on
Windows 9X (not that I believe people pay attention to warnings ;-).
