[patch] Remove DEFAULT_SHORT_ENUMS.

[Geoff Keating]

	* opts.c (decode_options): Don't use DEFAULT_SHORT_ENUMS.
	* system.h (DEFAULT_SHORT_ENUMS): Poison.
	* config/cris/cris.h: Remove a comment about
	DEFAULT_SHORT_ENUMS.
	* config/ip2k/ip2k.h: Likewise.
	* doc/tm.texi (DEFAULT_SHORT_ENUMS): Remove.

This is OK.
