 # ------------- mkdir required for win32 compatibility ------------
 # WIN32 mkdir takes only one argument, POSIX takes two.
 # #include "misc.h" where mkdir is required.

-# SYNOPSIS
-#
-#   AX_FUNC_MKDIR
-#
-# DESCRIPTION
-#
-#   Check whether mkdir() is mkdir or _mkdir, and whether it takes one or
-#   two arguments.
-#
-#   This macro can define HAVE_MKDIR, HAVE__MKDIR, and MKDIR_TAKES_ONE_ARG,
-#   which are expected to be used as follows:
-#
-#     #if HAVE_MKDIR
-#     #  if MKDIR_TAKES_ONE_ARG
-#          /* MinGW32 */
-#     #    define mkdir(a, b) mkdir(a)
-#     #  endif
-#     #else
-#     #  if HAVE__MKDIR
-#          /* plain Windows 32 */
-#     #    define mkdir(a, b) _mkdir(a)
-#     #  else
-#     #    error "Don't know how to create a directory on this system."
-#     #  endif
-#     #endif

-# This is what autoupdate's m4 run will expand.  It fires
-# the warning (with _au_warn_XXX), outputs it into the
-# updated configure.ac (with AC_DIAGNOSE), and then outputs
-# the replacement expansion.
-
-
-# This is an auxiliary macro that is also run when
-# autoupdate runs m4.  It simply calls m4_warning, but
-# we need a wrapper so that each warning is emitted only
-# once.  We break the quoting in m4_warning's argument in
-# order to expand this macro's arguments, not AU_DEFUN's.
-
-
-# Finally, this is the expansion that is picked up by
-# autoconf.  It tells the user to run autoupdate, and
-# then outputs the replacement expansion.  We do not care
-# about autoupdate's warning because that contains
-# information on what to do *after* running autoupdate.
