_______________________________________________________
Details:
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.
