Makefile.pre.in contains extra slash before $(DESTDIR) in two locations
as in the following:
sharedinstall:
$(RUNSHARED) ./$(BUILDPYTHON) -E $(srcdir)/setup.py install \
--prefix=$(prefix) \
--install-scripts=$(BINDIR) \
--install-platlib=$(DESTSHARED) \
--root=/$(DESTDIR)
This causes Cygwin builds to fail if DESTDIR is set as follows:
creating //tmp
error: could not create '//tmp': No such host or network path
The following Open Group Specification:

A pathname that begins with two successive slashes may be interpreted
in an implementation-defined manner,...
IMO, these extra slashes should be removed as indicated in the
attached patch. OK to commit? If so, to which branches?
