That's correct. A quick look at the output of 'set' in a DOS window
would have shown you that.

You disregarded the advice found directly above this line, and edited
you djgpp.env. It didn't help a bit, and you should unzip a fresh
copy, right now.

  ^^^^^^ This 'doskey' will never be executed, because of the 'goto'
right before it.

These two lines won't work as advertised. Nothin in the ':COMMON'
section of your autoexec.bat is ever executed, if you boot into
Windows. The call to 'win.com' has to be the absolutely *last* thing
to be done by autoexec.bat, for the rest of autoexec.bat to work.

The path setting put together by these lines will cause trouble.  You
have c:\BC45\bin in the path *before* c:\djgpp\bin. That cannot work
properly. Typing 'make' will find Borland's make.exe, not the one that
came with DJGPP, and same for 'cpp.exe', as well.

As a rule of thumb: if different C compilers are installed on one box,
only the one mentioned *first* in the PATH will work reliably.  All
others will show quirks. You need to be more careful setting up things
for such cases, which is one of the reasons that DJGPP still doesn't
have an automated 'setup.exe' or similar: it's nearly impossible to
understand all those subtle things that may be going on in a user's
autoexec.bat.
