[PATCH 04/17] Regex: Fix use of or add RE_ENABLE_I18N.

This patch makes better use of RE_ENABLE_I18N so that variables needed
only in that case are not declared otherwise. This avoids "unused variable"
warnings from various compilers.

2017-11-27         Arnold D. Robbins     <>

	* posix/regex_internal.c (re_string_reconstruct): Fix use of and/or
	add #ifdef RE_ENABLE_I18N.
	* posix/regexec.c (check_arrival_add_next_nodes): Ditto.
