The directory structure should not matter.

If I look at my Makefile.in I see

	VPATH = $(srcdir)/..:$(srcdir)/xmltok:$(srcdir)/xmlwf:$(srcdir)/xmlparse

(in line 301) and the same is true for the generated Makefile. This is
different from what you are reporting.

Do you have the leading / in your Makefile.in also ?

If yes it is damaged, IMHO. If not we have a very weird situation, because
the
transformation from Makefile.in to Makefile should leave the above line
alone.

Documentation bug.
