I've grepped the sources and there is another instance of this
problem, in that same file (src/makefile.w32-in):
   @cmd /c rem true

This sentence must not be executed in my current builds because I've
not had to touch it for my build to succeeded.  But if the sentence is
executed under some circumstances, the same problem will crop up.

So here is a new version of the patch which fixed that case too and
includes an informative commentary:
