This is a duplicate of bug #17752  --verified fixed in the latest CVS as a result of that fix.

We just stumbled over the same bug when upgrading from 3.80 to 3.81. As additional data point, I verified that reverting the change in implicit.c from 1.40 to 1.41 in a version freshly checked out from CVS fixes it (in our project -- and don't ask me why ;). This is the change I made:

aragon: .../tools/make > cvs diff -u

Given a directory containing only a file T.in (any contents) and a Makefile with the following contents

%.out: %; touch $@
%: %.in;touch $@
.PHONY: good bad
good: T T.out
bad: T.out T

then running "make -r bad" with GNU make 3.81 gives

make: * No rule to make target `T.out', needed by `bad'.  Stop.

On the other had using 3.80, it produces the expected results.
touch T
touch T.out

The change from version 1.40 to 1.41 of implicit.c which has the following log message
revision 1.41
date: 2004-09-21 13:23:12 -0700;  author: bosk;  state: Exp;  lines: +3 -1;
Fixed bug in implicit rule prerequisite evaluation code. Added test.

is at least partly responsible for the regression. Making just this change causes the modified make to give the error message. However both 3.80 and 3.81 manage to build the 'good' target, but the modified one gives

touch T
make+: * No rule to make target `T.out', needed by `good'.  Stop.
