>Environment:

	FreeBSD 4.0-CURRENT, probably any ELF-based system would show
	the problem.

>Description:

	The port fails to build with doubly defined references while
	linking w3c-libwww-5.2.1/LineMode/src/www:

>How-To-Repeat:

	# cd /usr/ports/www/libwww
	# make

>Fix:
	
	The problem stems from patch-ad, which inserts dummy
	declarations into Library/src/HTML.c instead of headers.
	Removing it allows the build to complete, but it does not
	create the files lib/libwww.so and lib/libwww.so.6.0.  In this
	connection I note the following log for patch-ad:

	revision 1.1
	date: 1998/12/25 14:52:05;  author: jseger;  state: Exp;
	Include a dummy version of the HText Interface so that the shared library
	links with other programs correctly.

	PR:             ports/9116

	It appears that it would be better to include these stub
	versions as a separate object file so that programs which
	include these functions will link correctly.  I don't
	understand why it doesn't create the shared libraries;
	possibly this is due to a different bug.
