Subject: [PATCH] [multiple changes]

2000-07-20  Zack Weinberg  <zack@wolery.cumb.org>

	* tradcpp.c (main): Don't munge -D options.
	(make_definition): Bring -D handling in line with cpplib.
	(do_define): Strip all leading whitespace from macro definitions.

2000-07-20  David Billinghurst <David.Billinghurst@riotinto.com.au>

	* Makefile.in (tradcpp): Depend on intl.o and version.o.
