My understanding is that programs using a GPL header need to be released
as GPL, but I don't believe they have to be only GPL, the dual-license
should cover the requirements. If someone wanted to redistribute the
code from the new header dis-asm-compat.h as BSD only, they would
probably have to get rid of the GPL-only dependencies though. But again,
this is only my understanding, and “I am not a lawyer”.

If compiler.h is just needed for the “unused” attribute, I wouldn't mind
doing that.
Thanks,
