Log message:
	port some fixes from 4.5:
	return values after gcc_unreachable for Solaris cc
	use form of x86 lock that is compatible with old and new assemblers, without autoconf
	support older Darwin systems unconditionally with-regard-to branch islands and alignment/common, again without autoconf
	(remember, because we build binary distributions, we are building cross compilers, and autoconf is therefore broken)
	remove more LTO
	always PIC (Darwin)
	gcc_unreachable for kernel flags (Darwin -- we surely are not portable to Darwin kernel at this time -- the runtime..)
	fix ENUM_BITFIELD for portability to other than gcc (Solaris cc)
	Maybe this is enough to move Solaris to 4.7; we'll see.
	
	I am not really certain about then gengtype-lex.l change.
