OK.  So going this direction (PARAMS instead of PROTO) is another
step towards making gcc conform to the rest of the GNU world.  Good.

Quite likely.  libiberty was only recently converted to autoconf.

Agreed.  Luckily this stuff is generally not found in the meat of the
source files (which would bring the merge issues into play).

Basically sounds good.  And as you say, we can take small steps
instead of trying to do everything at once.

One might consider moving the PROTO conversion later in the process.
That way we'd know that we have a workable solution before we go change
almost every C source file in the distribution.
