That would in some usages have influence on linking order, which
will be a disaster to track down.

But any speed improvements in filter* functions would be most welcome.
During a linux kernel compile 2 or more filter* functions is used for
each single target visitited. On top of this a number of filter* functions
is used for each Makefile.

Yup, it's open source. But not enough time :-(
