As of the latest CVS, parallel jobs should work on Windows.  However, note that the jobserver feature does not work so parallelism is restricted to pre-jobserver capabilities (recursive invocations of make are all run with -j1).

I'm closing this patch.

It sounds good to me (detecting enhanced cmd.exe).  But, someone needs to implement this and we need to test it across various versions of Windows.

I'm marking this "Need Info".

Sorry Paul I should have been more clear. We should detect the host on Windows (maybe call version.dll) and if we are running on Win2k or higher then we should try to use cmd.exe if a unix shell is not there. Older Win9x are just going to be out of luck for -j.

cmd.exe and not should be used.

The problem appears to be that while newer versions of Windows provide a that can handle advanced features, older versions still do not.  So, what should we do here?  Can make determine at runtime which level of it has access to?  Or should there be a configure/compile-time option to specify which one make should assume?

make -j currently requires a Bourne shell on Windows. This isn't actually necessary, and it appears to be caused by ignorance of the enhancemente of the Windows command prompt on its ancestor, the DOS prompt. The attached patch (targetting mingw32-make-3.80.0-3) fixes this
