I'm not 100% sure, but I think you need to link with -pg too.  At least, that's
what I do and gcc hasn't complained about unnecessary flags yet.  Also,
make sure the program runs all the way through and exits normally, and
make sure that you are running 'gprof <prog>', not 'gprof <prog.exe>'.
Profiling should output a file called 'gmon.out' in your run directory--make
sure that you haven't moved or deleted it.

The DJGPP info docs include a section for gprof.
