+
+ * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
+ (AS_INIT): Output shell initialization there. Removed optional
+ parameter. Expand _AS_SHELL_FN_SPY.
+ (AS_INIT_WITH_SHELL_FN): Removed.
+ (_AS_SHELL_FN_SPY): New macro.
+ (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
+ macros.
+ (AS_SHELL_SANITIZE): Remove loop to find better shell
+ and documentation for the parameter.
+ (_AS_DETECT_BETTER_SHELL): Move it here.
+ (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
+ (_AS_RUN): Move it here, support testing with eval.
+ (AS_REQUIRE_SHELL_FN): Require shell functions when
+ it is used.
+ (_AS_LINENO_WORKS): Put around braces, we do not
+ trigger the bash bug anymore.
+ * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
+ use AS_INIT_WITH_SHELL_FN.
+ * bin/autoconf.in, tests/wrapper.in: Regenerated.
+
+2004-01-30 Paolo Bonzini <bonzini@gnu.org>
* bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
* doc/autoconf.texi: Don't say that the third parameter
