Yes. There is a way to detect that. I'll look into this and get back with a

Definitely. Do I have to change the copyright message on the cfiles myself, or 
the gdb folks do it while including them into the gdb cvs tree? I have 
already signed a blanket copyright disclaimer for gdb contributions from 
myself as an individual. I'll have to sign one more for my company, 
LinSysSoft.
