# AC_PROG_MKDIR_P
# is a backport of autoconf-2.60's AC_PROG_MKDIR_P, with a fix
# for interoperability with automake-1.9.6 from autoconf-2.62.
# Remove this macro when we can assume autoconf >= 2.62 or
# autoconf >= 2.60 && automake >= 1.10.
# AC_AUTOCONF_VERSION was introduced in 2.62, so use that as the witness.
