glibc/pwd/fgetpwent.c
Roland McGrath c66273aae5 * nss/nss_files/files-parse.c (parse_list): Reset ELT for elements
after the first!

	* nss/nsswitch.c (__nss_database_lookup): If nsswitch.conf is missing
	or doesn't mention DATABASE, use an internal default equivalent to
	"DATABASE: compat [NOTFOUND=return] dns [NOTFOUND=return] files".
	(nss_lookup_function): Call nss_new_service as needed.
	(nss_parse_file): Don't bother calling nss_new_service here.

	* grp/fgetgrent.c (LINE_PARSER): Pass zero SWALLOW arg for fields.
	* pwd/fgetpwent.c: Likewise.
