The bug I was talking about didn't do anything to the timers, it just
caused the profiling code to try to write to the monochrome display,
which will surely slow down any program.

In DJGPP v2.02, there was another problem wth profiling, but it didn't
slow down programs, AFAIK.

One way is to look at the header file include/sys/version.h.

That is also very old.  But Gprof itself couldn't be the reason for
slow-down, because it is only run (by you) after the profiled program
exits.

The DJGPP mini-FAQ, posted weekly to comp.os.msdos.djgpp, shows the
latest versions of everything.

One way of finding out what versions do you have installed, is to look
at the *.ver files in your manifest directory.
