	I believe the GPLv3 issue is correct.
	Two other reasons I have heard mentioned in various
	1) clang has better diagnostics, both for users and compiler
	2) over the years, "extensions" have crept into GCC.  Many
were/are there for a reason; many can be ignored or turned off.
However, doing so breaks various programs (either when building or
running),  "Why?" is above my pay grade.
	_As I understand it_, clang has few such extensions and those
it does have are less necessary.
