Log message:
	Initial changes to compiler and libraries to make WIDECHAR big enough
	for current Unicode.
	Unicode escapes in char and text literals:
	W'\U10FFFF' = VAL ( ORD ( 16_10FFFF ) , WIDECHAR )
	Legal in nonwide literals, but value must be in range, e.g. \U0000FF.
	These are hard-coded in the compiler (m3front, m3cc(gcc-4.7)
	Library changes (m3core) adapt on recompilation to the WIDECHAR range of
	the compiler used to compile them.
	Debugger adapts at its runtime to the WIDECHAR size of the code it is
	debugging, but everything in the link closure needs to be recompiled
	by a compiler with the same WIDECHAR size.
	To bootstrap:
	1) Compile m3front and m3cc with an older compiler.
	2) Compile m3core with the compiler produced by step 1)
