You are right about MSYS Make, but MSYS is not MinGW, and AFAIK the
patches to Make done by the (now defunct) MSYS team were not
contributed upstream, so we don't know what they changed.

Note, however, that MSYS Make has other goals than MinGW: MSYS is
supposed to emulate Unix enough to allow use of unaltered Unix
Makefile's to build MinGW ports.  So the issue that you are talking
about is an explicit goal for MSYS, more-or-less its raison d'être.
Thus, it is not surprising that MSYS does this.
