By link, you mean for dxe3gen?  If yes, then I tried that.  And no, the 
project is not open unfortunately.

Syntax for building the DXE: 'dxe3gen -V -U -E _dll_Entry -lstdc++ -lgcc 
<my objs> <my dxe>'

The interesting thing about the -lstdc++ -lc is that I'm using the 
Andrewwu cross-compiler which has mingw32 packaged and ready to go on 
Windows.  However, I had to copy libstdc++.a and libgcc.a from 
C:\djgpp\lib\gcc\i586-pc-msdosdjgpp\4.9.4 to 
C:\djgpp\i586-pc-msdosdjgpp\lib which I suspect is incorrect and could 
be part of my issue here?
