The pragmas which aren't portable could be protected by appropriate macros
and it would be the responsibility of anyone using non-gcc compilers to
provide appropriate support for their environment.
I appreciate that it's not terribly significant, but anyone who needs
to provide support for a 32 bit PV guest on a 64 bit host would
need code remarkably similar to this and so I don't think it's Linux
specific. That's why I suggested re-locating it because it might make
life simpler for other developers in the future.
If it's really not a good idea to re-locate it, then I think a BSD license
would be an acceptable substitute for my purposes.
Thanks,
