Yep, any command capable of removing a subdirectory and all of its
contents on any system has this behavior.

Well, $(OBJDIR) is hardcoded to ".\objs" in line # 53, so I would say
it is not actually a problem of current Makefile.b32.
On the other hand, if things can be done more safely I'm all for it.

OK.

Currently I have no Borland compiler installation to test any changes,
so it is better if you introduce required changes to the removal of
$(OBJDIR).

Hmmm, now I start to understand Gün's words in

Given your words, it seems that he was referring to the command
itself. There was no answer, and it seems none of us have had time yet
to make the change happen.

Would it be enough to use "md" and "rd" to avoid CygWin's "rmdir.exe" ?

In any case, please, test and adjust it as you believe it should be done.
