Subject Re: activemq Cygwin build and GPL

If you can figure out how to make the build work with MinGW you can
submit a patch to add that as an option in the configure script.

Really we only endorse using MSVC on Windows as we have had nothing but
trouble with Cygwin and MinGW.  

Patches are welcome.
