Why? Does gprof has some problems that it's not providing the
information that you need?

So you want to use a profiler under Linux to find out why it is
slower under Windows. Sounds a bit strange to me. (FWIW:
Windows is significantly slower than Linux for many operations,
including file operations---anything involving reading from or
writing to disk will run slower under Windows.)
