Re: multiple wildcards in a static pattern rule

[Noel Yap]

BTW, I think the action would be better as:
        umask 333  &&  cp $< $@

Rationale:
  1. umask'ing will create the target immediately with read-only permissions 
with no window for writing (even if you're not concerned about the security 
issues, I think it's still much cleaner)
  2. using '&&' halves the number of shells per target created; ';' would do 
the same thing but would have the consequence of allowing the 'cp' to execute 
if the umask failed.

HTH,
Noel
