    Add AC_USE_SYSTEM_EXTENSIONS providing needed WTMPX_FILE define
    
    The WTMPX_FILE is only defined under __USE_GNU conditional
    compilation. Autoconf provides AC_USE_SYSTEM_EXTENSIONS
    to enable platform extensions.
    
    It must be expanded before any other macros that uses the compiler.
    To reduce the risk of being misplaced, the statements have been
    grouped (mostly) as per the GNU standard layout.This macro
    requires Autoconf level 2.60 or later.
    
    The compilation failed under a GNU-Linux OS.
