Bug or not? % character not expanded in phony targets
It appears that the pattern matching character ("%") is not expanded in
phony targets.
For example, given a GNUmakefile like this:
TARGET_NAMES:=phony-a phony-b phony-c
d : $(TARGET_NAMES)
phony-% :
@echo Phony target is $@
.PHONY : $(TARGET_NAMES) d
...making "d" results in nothing being echoed.
However if you remove $(TARGET_NAMES) from the .PHONY rule (i.e. render
that list of targets non-phony), then the pattern rule (phony-%) is
correctly expanded and the echo command is executed.
Is this desired behavior?

Re: PATCH: .SECONDARY target with no dependencies does not work correctly.
"Paul D. Smith" [EMAIL PROTECTED]: This is obliquely stated in the documentation: `.SECONDARY' The targets which `.SECONDARY' depends on are treated as intermediate files, except that they are never automatically deleted. *Note Chains of Implicit Rules: Chained Rules. `.SECONDARY' with no prerequisites marks all file targets mentioned ^^ in the makefile as secondary. Note the second paragraph. The targets you give aren't mentioned in the makefile; they're built using implicit rules. Yes, but aren't all explicitly mentioned targets considered secondary anyway? If so, it seems like ".SECONDARY: " serves no purpose... For the complex Makefiles I'm working on now, intermediate deletion was causing deletion of object files which should not be deleted, and I decided to just turn it off entirely. However, without .SECONDARY behaving as I'd like it to, I don't see how to acheive this. I agree with you, however, that this is a strange restriction and this area needs to be revisited, for all of PRECIOUS, INTERMEDIATE, and SECONDARY. I'll file an enhancement request about it. Thanks.

Re: make 3.79 status problem
%% Regarding make 3.79 status problem; you wrote: alt Doing a "make -q" with the following makefile returns a 1 status alt where it should really return a 0 status. Can this be fixed? I alt know I could wrap an ifndef expression around the ALL commands, alt but I use this a lot. Can you give me a more complete example? If you have that makefile and you run make with -q it _should_ exit with 1, since it needs to build "foo"... ? You must have some other setup beyond just the makefile. -- --- Paul D.
