This code needs thread-safe C++ runtime, and Cygwin gcc currently lacks
that. Even if you build a thread-safe cygwin, it may not work until the
C++ runtime library is built using pthreads. Unfortunately, the pthreads
implementation in Cygwin/winsup is not mature enough to build thread
safe C++ runtime yet, but that's something I'm going to work on soon.

It does work under Mingw when you -mthreads to compile and link (which
links in the thread-safe C++ runtime).

Mumit
