 If I'm not mistaken, we need our custom make on Windows anyway, since LO 
build fails with the cygwin one for some reason (may or may not be our fault, 
I don't know). Moreover, this is most probably not going to work anyway, 
since it's the developer who runs the make, not the buildsystem (eventually, 
after we get rid of dmake). And Makefile.top has shown that make forwarding 
does not quite work as it should.

 I have not tried, the commands are rather LO-specific in some cases, so we 
need a patch anyway. I also consider it to be a bit of an ugly hack.
