Yes.

No --- because a properly designed library will have essentially only
one function per module, or only put those together in a single module
that you would always need either all of, or none.

Impossible to tell without seeing your program.  Try to cut it down to
the minimal example and show that here, including the gcc commands you
use to build it.

Or pass the '-Wl,-verbose' option in your gcc link command, which will
have the linker output enormous amounts of debug printouts showing you
exactly what it's doing, and why.  You'll want to redirect that to a
file (--> DJGPP's "redir" utility).
