Or a Windows > executable from cygwin? Our build and test environment for windows is cygwin. This is a Python test script running a native windows executable using subprocess.Popen(). The LIBPATH I'm building is for the executable's environment. We're looking to possibly replace cygwin with MinGW at some point in the future. In the past, we've always equated "cygwin" and "windows" in our build scripts, but now that we're thinking MinGW-ish thoughts, that's looking like a sub-optimal strategy. > LIBPATH should be in the format desired by the consumer.
