It's something we all dream of. Having written many such module
loaders for Turbo C++ in the past, I would try and find the time to
write same for DJGPP if I understood the COFF format.

You'd need to put some level of debug info in the executables, so as
to find them symbols, or change the stub to be a "runtime linker",
such that we just link in standard .o and .a files. Unresolved
references point to the NULL minefield, in case they get called before
being resolved.

Also, there should be the power to query a module's symbols and access
them numerically (like an array of void*). Thus, we can do things like
printer drivers as well.
