	If you insert #ifndef __cpluscplus__ wrappers, wouldn't the
declaration depend on the compiler which is processing them, and thus
vary between the .cpp and .m files?

	The unix version works, but because OS X uses different
conventions for storing the resource and finder files, it isn't
very useful. i.e. You cannot access programs stored on MacOS X
mounted HFS volumes.

	The structures I put in extfs_MacOSX.cpp are similar,
copyright wise, to the stuff in macos_util.h. They are based on
information published by Apple (whether from Inside Macintosh,
or from the Apple Universal Headers).

	I suspect that if we rename or obfuscate the stuff I have
typed in, that will be enough to get around any copyright issues.
But then again, I am not a lawyer, and Apple might be monitoring
this very mailing list :-)

	True, but B2 emulates an old Mac, running an old MacOS.
That is what it could mean.

	Or maybe something like a bank vault or a museum?
Something that stores old stuff? (both shiny-new, of course!)
