Description: with VPATH generic rules are not fired when dependents are
newer than targets.
Reproduction: To reproduce this bug use the following Makefile:
--
VPATH=..
%.target : %.source ; cp $< ../$@
showVPATHbug.target: showVPATHbug.source
--
Make the target, then touch the source. Another make fails to update
the target. Note that if the generic rule is replaced with the
following specific rule, then the bug goes away:
--
VPATH=..
showVPATHbug.target: showVPATHbug.source
cp $< ../$@
--
I have also noticed that with GPATH the target is always rebuilt.
Please let me know if there is a workaround for this. Thanks for the
otherwise great CygWin software,
