This is something I would like to see corrected. There needs to be a
simple way to express that two targets are created together using the
same rule without resorting to patterns. The only question would be the
syntax.
Two possibilities come to my mind either grouping the targets:
[ foo bar baz ] : biz
@...
Or to use a different separator from the plain colon like:
foo bar baz &: biz
@...
&: is only a random choice. There may be better choices.
And as I pointed out recently this is a big concern when start trying to
parallel makes. Having it generate the files multiple times with
parallel make may mean you are generating it when someone is reading the
generated file.
