    Add XORG_WITH_M4 macro
    
    Originally from XCB, this macro checks for the presence of m4 or gm4
    which supports -I dir.
    
    The AC_PATH_PROGS_FEATURE_CHECK autoconf macro requires autoconf 2.62.

    Bump minimum Autoconf required version to 2.62
    
    The main motivation is to catch-up with the development reality and
    allow use of features in Autoconf 2.62 as well as Automake 1.11.
    
    As usual this means no features found only in versions above those
    specified are allowed.
    
    This is implementing the policy change which is described in:
