The last command should create two files: gmon.out and bb.out
which together contain the information you need.
The file bb.out is a text file, but gprof cannot read it.

Thus you can transform its contents into a binary file.
To perform this, you have to use the program bbconv.pl which is part
of gcc distribution.  Either you have it as part of your instalation,
or you have to extract it from gcc source tarball.
(If you use cygwin, the source tarball should be installable through
setup.exe.)

To run bbconv.pl, you need perl.  I'm sure perl for Windows is available
in various ways, cygwin being one of them.

When bbconv is sucessfully run and a non-empty BB-DATA file is created,
you can run gprof:

Good luck,
