2013-05-03  Carlos O'Donell  <carlos at redhat.com>

	* intl/dcigettext.c (DCIGETTEXT): Skip translating if _nl_find_msg returns -1.
	(_nl_find_msg): Return -1 if recursive call returned -1. If newmem is null
	return -1.
	* intl/loadmsgcat.c (_nl_load_domain): If _nl_find_msg returns -1 abort
	loading the domain.
