(I'm bcc'ing a copy of this to our contact at Diab. Since money has
been offered to pay for what amounts to the integration of these
patches, I figure they'll want to hear about it.)

It gets worse.
In the next release of our ColdFire toolchain, we shipped a GCC with ColdFire
specific work in it, and dropped GDB support for the Diab changes -- this was
a last-minute decision to make a deadline, but the fact remains that I have
orphaned changes in dwarfread.c, which only show up in our first ColdFire
release branch.

Maybe. I remember having to tweak them around quite a bit. There was a
problem with dynamic loading (which we do for vxworks) because of some
global variable that didn't get reset often enough.
