This usually indicates a mixup of libraries from different versions of 
GCC.

The usual way to handle these problems is to have two separate 
directories, one for GNAT and another for DJGPP, and have a simple batch 
file that switches between them by pointing the DJGPP variable to a 
suitable place.  If there are duplicate files that both environments 
need, simply copy them.

If you run this on Windows 9X, you can create two different shortcuts 
that both invoke a DOS box, but make it run a different batch file, so 
that each box will be set up for a different development environment.
