commit 2b85923e0b06f7f633b7f9f18bdec2b16ec5d958
Author: Ralf Wildenhues <address@hidden>
Date:   Sun Oct 26 18:50:17 2008 +0100

    Minor file checking optimization: set_dir_cache_file.
    
    * lib/Automake/FileUtils.pm (set_dir_cache_file): New function.
    * automake.in (require_file_internal): Instead of resetting the
    cache when a file has been installed, simply correct the cache
    using set_dir_cache_file.
