Thanks for looking into this.

Gosh, I _hate_ incompatible changes that don't leave any escapes like
a command-line option to get the old behavior!

We have a similar problem in the library sources (djlsr203.zip), as
reported by Mark Elbrecht a few days ago.

This sounds like the lesser-evil solution.  You can put #ifdef in the
assembly source, and have Make determine which version of Binutils is
in use.  Here's a starting point for Makefile magic to do that:

  BNU_VERSION := $(shell as --version | sed -n 's/^GNU assembler //p')

(This is only a starting point, since you will need to define
BNU_MAJOR, BNU_MINOR and such likes, given BNU_VERSION.)

Then use "gcc -DBNU_MINOR=..." to get this info into the
preprocessor.
