Follow-up Comment #2, bug #29814 (project make):
Make will use VPATH (or vpath) for library search as well. So, on a multilib
system, you can add:
vpath lib% /...whatever...
to specify where to look for libraries, for example.

Since the makefile is a real file, you shouldn't be marking it phony. The

That requires changes to every makefile. With my proposed patch series,
distributions that want to support multilib would be able to configure make
to use the correct standard search directories for the system's primary
architecture. A user who

The GNU make manual both supports and defeats Matt's statement.
A phony target is one that is not really the name of a file.

Once this is done, `make clean' will run the commands regardless of
whether there is a file named clean.

Follow-up Comment #5, bug #28983 (project make):
I don't understand how the second quote defeats my statement. The point is
that marking the clean target phony prevents the accidental existence of a
file by that name from confusing the build system. If you're trying to argue
from that quote
Follow-up Comment #6, bug #28983 (project make):
The following tests show that .PHONY's pre-requisites are normally rebuilt
regardless of existence of a file with the same name.
This works,
$ cat test-force.mak
default: file.o
.PHONY: file.o
file.o:
echo Building $...@... $@
