Index: ChangeLog
from  Akim Demaille  <address@hidden>
        * m4/depend.m4 (AM_DEP_TRACK): Use AC_SUBST([AMDEPBACKSLASH])
        normally, what is wrong is that automake outputs a variable
        definition for it, hence...
        * automake.in (scan_one_autoconf_file): don't.
        
        * m4/depout.m4 (_AM_OUTPUT_DEPENDENCY_COMMANDS): New, extracted
        from...
        (AM_OUTPUT_DEPENDENCY_COMMANDS): here.  Adjust.
        Use AC_CONFIG_COMMANDS.
        (_AM_OUTPUT_DEPENDENCY_COMMANDS): Use AS_DIRNAME and AS_MKDIR_P.
