commit 9379b7024cd6d481e7a9487529e98230fc260a91
Author: Ralf Wildenhues <address@hidden>
Date:   Thu Aug 14 23:29:23 2008 +0200

    Fix AC_*_TARGET_TOOL macros.
    
    * lib/autoconf/programs.m4 (AC_PATH_TARGET_TOOL)
    (AC_CHECK_TARGET_TOOL, AC_CHECK_TARGET_TOOLS): Require, do not
    warn about previous AC_CANONICAL_TARGET.
    (AC_CHECK_TARGET_TOOL): Add missing `$' making the macro
    unusable in the non-cross-compiling case.
    * NEWS, THANKS: Update.
    Report by Dave Erickson.
