I have no problem if the standard legalese is added to each file in the
copy in GDB. I didn't add it so far because it seems redundant. The Linux
kernel mostly doesn't have it either, and it's under the GPL as well.

There's the LICENSE file in the UAE distribution (the GPL), and the
statement in the README which also says that the source code is distributed
under the GPL.
You can also have my word for it :)

There is a bit of 040 support in the latest version, but nothing for the
ColdFire.

Yes, the FPU emulator could be improved. It's the weakest part of the thing.
