This is out of date, unsupported, and probably unstable. Use at your own risk.
A better option is to grab the 3.8.0 binaries, which are linked against the current (beta 20.1) version of Cygwin, or to use the current Cygwin version to compile your own binary from the sources.
With all those warnings out of the way, here are the binaries:
Win32 binary of dxpc 3.7.0
Beta 18 version of CYGWIN.DLL (required)
