Hi Sam, Paul, Guenther,
I've rumiated this idea for some months already: I can use ?=, as long
as I force users to add a dummy -R to the command line. The dummy -R
will only be required if they GNU make(1) is too old (but everyone's
make(1) is too old, because the requirement will be 4.5, so...). That's
a minor inconvenience, but anyway, I should do it even when 4.5 is out
and I move to ?=, because otherwise people running on old make(1) would
have a broken build system, so I really need to force people to specify
-R.
What do you think about it?
Here are the patches for the Linux man-pages build system. Please have
a look at them. :)
Have a lovely day!
Alex
P.S.: Guenther, I just CCd you in case you were curious about this. ;)
Alejandro Colomar (3):
GNUmakefile: Require the user to specify '-R' if their make(1) is too
old
share/mk/: Use ?= assignments for user-facing variables
GNUmakefile: help: Show only variables assigned with '?='
