  * Remove AC_C_CONST
  It was breaking the build on Windows. The problem was that we included
  stdio.h which gave a prototype for some functions (e.g. remove), then
  the AC_C_CONST meant that we did
      /* Define to empty if `const' does not conform to ANSI C. */
      #define const /**/
  and then we included io.h which gave prototypes that, due to const
  being removed, conflicted with the earlier prototypes.

    M ./configure.ac -3
