Not a problem, surely? If you're not using GNU make, then it'll look for
a (presumably non-existent) file called ".PHONY", and hence the rule will
trigger anyway, with exactly the same effect.
Wrong way round: the syntax is
.PHONY: install uninstall
so a non-GNU make will just ignore the line (unless you're dumb enough
to say 'make .PHONY' :-)).
I notice that the GNU make info manual claims that this:
install uninstall: FORCE
# rule with no prerequisites or commands, and there's no file 'FORCE':
FORCE:
has the same effect, and doesn't rely on GNU make extensions.
We should check that that works on Mac OS X and use that, I think.
