linux下编译交叉工具链的工具源码

2000-08-27  Ulrich Drepper  <[e-mail]>

	* intl/dcgettext.c (DCGETTEXT): Remove _nl_find_language in code
	to determine invalid locale name.
	* locale/findlocale.c (_nl_find_locale): Likewise.

2000-08-21  Ulrich Drepper  <[e-mail]>

	* catgets/catgets.c (catopen): Filter out env_var values with / if
	necessary.

	* locale/findlocale.c (_nl_find_locale): Move test for unusable
	locale name after all getenvs.
