I fully understand.  I've gone through the experience myself of trying
to fit a too-large program into ROM for an embedded system and I was
counting each word.  But are you and the other embedded systems folks
being consistent here?

That is, have you verified that no other egcs change results in a 2%
increase in code size for little or no gain?  It's true that .eh_frame
is special in that it's clear the wasted space is just that, wasted.
But have we been carefully comparing space performance on old benchmarks?
If so, I haven't seen that much discussion.
