What steps will reproduce the problem? 1. Build the windows distros 2. Build the windows release zip files 3. Note that the library files needed for windows builds are not in the zip files

The solution is to correct the build.xml to include pthread*.dll and the libantlr3c.* (usually copied from the c:\mingw\lib directory). Also need to copy the header files for the pthread library and the header files for antlr.

For release 2.3 these were manually copied, but this needs to be changed in the normal build.xml process.

we don't support cygwin anymore.
