Was this program linked with DJGPP v2.02?

If so, then the profiling code there has a bug that manifests itself in 
the above way: the first function is shown to take 100% of the time, and 
the rest take 0%.  This info is bogus, don't make any conclusions based 
on it.

I can send you a patched source of a library module which is responsible 
for this.  You will need to compile it, put it into libc.a, and then 
rebuild your program and run it again.  *Then* the profile should make 
sense.
