I suspect this to be the core of your problem. You have a mixup of
different gcc versions on your system. 'cpp' is from gcc version
2.7.2.1 (a rather old one), while your 'gcc' is the up-to-date 2.95.2.
Possibly, other parts of the old compiler are also still lying
around. 'libgcc.a' is the most probable candidate for why you're
getting undefined references.

Looks like you didn't follow the installation instructions for 2.95.2,
closely, otherwise that copy of 'cpp' ought to have been deleted or
replaced by a newer one.

This seems not to the autoexec.bat that resulted in the 'set' listing
shown above.  Your PATH is a bit strange: you autoexec.bat doesn't add
the WINDOWS directories, but yet, they're there, in the 'set' output.
You can remove D:\djgpp\bin from your first 'path' command, the one
added by LBINSTDJ will put it where it belongs.

'setdjgpp.bat' is a rather old-ish method of setting up DJGPP, and you
should not generally execute it like you did ('call' is missing, in
front of it). The ctrl-Z character may cause everything below it to be
ignored, when executing the autoexec.bat.  Remove it, and the setdjgpp
call, and things may improve.
