X-Git-Tag: cvs/fedora-base~720
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e2fd3cbe085d9867710ee7b3d487c16c150fa204;p=platform%2Fupstream%2Fglibc.git

Update.

	* config.h.in: Add entry for HAVE_LIBIDN.
	* configure.in: If libidn add-on present define HAVE_LIBIDN.
	* Versions.def: Add entry for libcidn.

2004-03-07  Simon Josefsson  <jas@extundo.com>

	* resolv/netdb.h [__USE_GNU]: Add new AI_IDN ai_flags for addrinfo.
	[__USE_GNU]: Add new error code EAI_IDN_ENCODE for getaddrinfo.
	* sysdeps/posix/getaddrinfo.c: Add prototype for __idna_to_ascii_lz
	and define IDNA_SUCCESS.
	(gaih_inet): If ai_flags have AI_IDN, invoke __idna_to_ascii_lz.
	(getaddrinfo): Fix EAI_BADFLAGS test to include AI_IDN.
	All changes only applicable when glibc is compiled with the libidn
	add-on.
