I have recently tried to reinstall DJGPP on my PC, but I can't get
the compiler to work.

I have put the following two lines into the autoexec.bat file

SET PATH=C:DJGPP\BIN;%PATH%
SET DJGPP=C:DJGPP\DJGPP.ENV

as I was told.

I keep getting the following error:

"environment variable DJGPP points to corrupt
file 'C:\DJGPP\DJGPP.ENV'"

even though the file 'C:\DJGPP\DJGPP.ENV' is taken from the
delorie.com website and is untouched by me.

I have read every single reference and possible remedy to that error
on the DJGPP FAQ list, but I still get the same result. I've even
tried deleting DJGPP and reinstalling, but I still get the exact same
error. Does anybody have any idea how I can figure out what's wrong
here?
