Subject: Patch: minor hinfo -> dtable cleanups
Content-Type: text/plain; charset=us-ascii
Content-Transfer-Encoding: 7bit

Since hinfo.cc got replaced by dtable, some minor cleanups to
documentation and makefiles are in order. Patch is pasted below in both
gz.uue format and plaintext.

2000-08-13  Charles Wilson  cwilson AT ece DOT gatech DOT edu

	* winsup/cygwin/Makefile.in: add dtable.o to
	dependency list; remove hinfo.o from that list
	* winsup/cygwin/ROADMAP: replace 'hinfo' with
	'dtable' in sgml dependencies and comments
	* winsup/cygwin/fhandler-tut.txt: replace 'hinfo'
	with 'dtable' in the documentation
