From past experience if I remember correctly this looks like a problem

You did not read the GCC readme.djgpp file... Please go back to GCC
3.2.2 from the Alpha directory. 

This is probably the cause of the problem....

Did you read the readme.djgpp in the ...\gnu\gcc3.3 directory approx
line 143 (search for 2.04).

Yes, they are incopatible with each other and you need to use the
right C++ compiler.

The next alpha release will  fix the problem as noted in the GCC 3.3
readme file.

If the info above does not help then try the following:-

I would suggest that you check that all of the libs and exes of DJGPP
that you areusing are dated arround the 25-April-2003 (give or take
2-3 days). If you find any that are not dated then please do a dir on
them and include them in your response.

Please note:-
Do not mix the 2.03 and 2.04 object/lib files as they are not
compatible when dealing with C++ programs. 

If all else failes:-
1)  If the batch file is small please supply it
2) Do you have a small sample program (less than 20 lines) that I can
test with the 2.04 alpha release and with the latest build from last
weekend to see if the problem can be reproduced.
