Summary: Marking .PHONY dependencies as targets is a
regression against 3.80
Project: make
Submitted by: None

Open/Closed: Open
Component Version: 3.81
Operating System: None
Fixed Release: None
_______________________________________________________
Details:
Running "make foo" with a Makefile containing the following two rules
produces different results with make 3.80 and 3.81.
.PHONY: foo
.DEFAULT:
echo the target is $@
With 3.80, it prints "the target is foo", and with 3.81 it states that
"Nothing to be done for `foo'". This was caused by adding the following
line to file.c in int .PHONY case (line 675).
f2->is_target = 1;
This is a regression, since it breaks our makefiles, and I don't understand
why phonies should be considered as explicit targets unless there are actual
rules for them.
The ChangeLog mentions this, but it doesn't really explain why the change was
made.

* file.c (snap_deps): Mark .PHONY prerequisites as targets.
* implicit.c (pattern_search): When considering an implicit rule's
prerequisite check that it is actually a target rather then
just an entry in the file hashtable.
