Since the mingw32 +headers are very different, using the wrong cpp is a real problem. It is leaking +into configure through the CPP variable. Ultimately this leads to build +failures related to not being able to include a process.h file for pem-unix.c. + +The fix is to ensure we export a sane CPP value into the build +environment when using build targets.
