Yeah, the utility is called dxegen. You can find a basic dxe example
in the "tests" distribution of djgpp.

Here are a few of the pitfalls I've managed to avoid when playing 
around with dxe :-)

If you intend to load the dxe from within a c++ program you'll have to
surround the 
#include <sys/dxe.h> 
line by :
extern "C" { 
} 
definitions or you'll get a weird _dxe_load unresolved symbol at link
time. 

If the dxe file contains unresolved symbols, it won't work. BUT I've
found a workaround, which is to fully link the file you want to use as 
a dxe (so you get an exe) and use dxegen to export symbol main. This
seems to work, but I guess it's really pushing dxe to its limits. 
Maybe I'll have to switch to this dlx library which sounds promising.
