-# SYNOPSIS
-#
-#   AX_REQUIRE_DEFINED(MACRO)
-#
-# DESCRIPTION
-#
-#   AX_REQUIRE_DEFINED is a simple helper for making sure other macros have
-#   been defined and thus are available for use.  This avoids random issues
-#   where a macro isn't expanded.  Instead the configure script emits a
-#   non-fatal:
-#
-#     ./configure: line 1673: AX_CFLAGS_WARN_ALL: command not found
-#
-#   It's like AC_REQUIRE except it doesn't expand the required macro.
-#
-#   Here's an example:
-#
-#     AX_REQUIRE_DEFINED([AX_CHECK_LINK_FLAG])
