Looks like the call to strerror is from clearerr, so you didn't
actually return from clearerr yet.  If so, Emacs hangs in this line
from emacs.c:

  clearerr (stdin);

which would indicate that something is holding the standard input
handle of the Emacs process.  This could be the result of having
Cygwin installed and running Emacs from the Cygwin shell.

Can you try the following command, and see if it works?

 cmd.exe /c "start C:\cygwin\home\udalrich\emacs\emacs-23.1\bin\emacs.exe -Q"

If you can remove the Cygwin shell from PATH before running this
command, please do.

Btw, if you have Cygwin installed, why don't you use the Cygwin build
of Emacs?  In general, mixing Cygwin and native Windows executables in
the same environment is asking for trouble, because they are subtly
incompatible.
