Not today, sorry.
>Environment:
System: NetBSD cyclops 1.5Y NetBSD 1.5Y (CYCLOPS) #3: Tue Nov 6 08:30:46 EST 2001 rafal@cyclops:/extra/src-current/sys/arch/i386/compile/CYCLOPS i386
Architecture and Machine are i386, but I don't think this is an MD bug.

>Description:
	Assume we have a directory tree like the following:
		topdir
		topdir/foo
		topdir/foo/foo

	And assume that topdir/foo has a (already make) target file `bar'.
	A make from topdir/foo attempting to make `foo/bar' will fail to
	make the `bar' target in `topdir/foo/foo/' as make incorrectly
	finds `topdir/foo/bar', claims it's up to date and quits.

>How-To-Repeat:

	Attached below is a uuencoded .tar.gz file that includes a sample
	test case.

	Untar this file, cd to foo/ and type `make'.  

	It's expected that `make' will copy `foo/foo/Makefile.in' to 
	`foo/foo/Makefile' via the foo/Makefile target.

	However, with a make built from Nov 6th sources, `make' finds
	`foo/Makefile', declares it up-to-date, and does *not* run the
	rules to make `foo/foo/Makefile'.  

	This bites the xsrc build bigtime, as the Makefile-generating
	machinery uses similar rules to make Makefiles out of Imakefiles.

	Some investigation by Alasdair Baird have shown that sources of 
	October 31, 2001 are OK.. See the below URL.

	More details on how this affects xsrc can be found in the mailing
	list archives at:
