But this is a C++ program, right? (I assume this because you linked
it with -lgpp.) If so, you should call the source file dsweep.cc or
dsweep.cpp, otherwise GCC will compile it as a C program, and that
could very well result in unresolved externals.

You just mention the library names on the link command line, as if
they were object files (but put them after all the object files).

This is in general impossible. You cannot link DJGPP programs with
libraries or object files produced by other compilers.

I wasn't even aware that Make is part of this equation, since you
never mentioned it. The only reason I could think of is that you used
backslashes, and Make treats those as escape characters. Use forward
slashes instead.
If that doesn't help, you will have to tell more about the differences
between invocation from the command-line and from Make.
