Re: match-anything rule takes precedence over earlier rule

[Johan Bezem]

AFAIK, the "% : error" rule says, that all targets are depending on the
'error' target, so that is built first. The manual says:
> There can only be one set of commands to be executed for a file. If more

This is what you see, except for the error message; but then, maybe your
'exit' prevents the error message being printed.
Please remove the 'exit', and if necessary, use '-d' to see waht's going on.
Maybe you should consifer using double-colon rules for this, depending on
what you want to achieve with the %-rule.
