I don't know about APR capabilities when built with Cygwin.  Building
with MinGW uses APR's thread implementation for Windows, so yes
threads will be supported.

Whether to build APR with Cygwin or MinGW should follow the general
Cygwin/MinGW choice:

* Unix-y code in your application that requires emulation?  Cygwin
* No Unix-y code in your application?  MinGW

Note that you can't build APR as a shared library with 1.4.5, but that
will hopefully be resolved in the next release.  (That's already
supported in trunk.)
