     25 dnl sort alphabetically after any libtool, autoconf or automake
     26 dnl provided .m4 macro file that might get copied into this same
     27 dnl subdirectory. This allows that macro (re)definitions from this
     28 dnl file may override those provided in other files.

     32 dnl -------------------------------------------------
     33 dnl This macro overrides the one provided by autoconf
     34 dnl 2.58 or newer, and provides macro definition for
     35 dnl autoconf 2.57 or older which lack it. This allows
     36 dnl using libtool 2.2 or newer, which requires that
     37 dnl this macro is used in configure.ac, with autoconf
     38 dnl 2.57 or older.
