Ok, I guess the change might have been only for MinGW.

The attached makefile works with slashes under MSYS with Make 3.79.1. It
doesn't work with backslashes at all since I've used the "$(strip \)" trick,
but if you replace that with "\\" it will output the following error when
run a second time: "cannot create directory `c:\\progra~1\\foo': File
exists". I think Cygwin behaves like MSYS?

Unless my test makefile is flawed, it wouldn't help. :(
