  From "man gprof" under SunOS/UNIX I quote:

     A single function may be split into subfunctions for profil-
     ing by means of the MARK macro (see prof(3)).
 

  Unfortunately, I don't know yet how to use this macro nor whether it is supported by
  gcc/djgpp. However, it seems to do what you want....
