Subject: cc doesn't have the M option
Index:	bin/cc.c 2.9BSD

Description:
	The C compiler front-end doesn't have the 'M' option.  Note, this
	option is undocumented in 4.2 and 2.9, but many of the makefiles
	use it.
Repeat-By:
	Enter "cc -M foo.c" and you'll get an error message from ld.
Fix:
	Apply the following diff.
