1) Compile with -pg.  Yes, it is needed in linking!
2) Run the program, it creates a file gmon.out
3) run "gprof program".  This analyzes gmon.out using info from program,
   displays on screen.  I recommend "gprof program > program.prf" so you
   can analyze in detail.

Profiling timing results will be 0 under DPMI with V1.x, so you probably
should avoid DPMI when profiling.  Timing works under V2 and will be in
the next beta.
