Subject: [multiple changes]

2000-03-07  Neil Booth  <NeilB@earthling.net>

	* cppexp.c (struct operation, left_shift, right_shift,
	cpp_parse_expr): Change some "char"s to "U_CHAR"s, and some
	"int"s to "unsigned int"s.
	* cpplib.c (detect_if_not_defined, do_assert, do_unassert):
	Similarly.
	* cpplib.h: Update for above.
	* mkdeps.c (deps_init, deps_calc_target): Cast pointers
	returned from allocations.

	* cppinit.c (opt_comp, parse_options): New functions.
	(handle_option): Use parse_option to parse a single command
	line option, that possibly takes an argument.
	(cpp_handle_options): Sort the array of command line options on
	first invocation (non-ASCII hosts only).
	(print_help): Update.

2000-03-07  Zack Weinberg  <zack@wolery.cumb.org>

	* mkdeps.c (munge): Fix off-by-one bug and inconsistencies in
	backslash counting loops.  Problem noted by Matt Kraai <kraai@ghs.com>.
