Both methods work.
I can compile dxe2gen.cpp directly with gcc if I call libstdc++, or gpp will
call it automaticly.
Both versions seem to run OK.
The GPP made version is 15% larger.

Now I understand. GPP is a c++-flavoured compiler and GCC is a C-flavoured
compiler.
So libstdc++ is the standard c++ definitions library... I found all the info
under %DJGPP%\..\gnu\gcc-3.04\libstdcxx ... explains all about it. I just
need to have the time to read it all :-)
The problem is that many packages that have not been updated do not
understand the need to link with this library. Many makefiles just call gcc
for everything.

Is there a way to configure GCC to link with libstdc++ automaticly or send
the code to GPP if needed?
If this should be he case already, it appearantly did not work in my case...
