# ===========================================================================
#
# SYNOPSIS
#
# AX_CONFIGURE_ARGS
#
# DESCRIPTION
#
# Helper macro for AX_ENABLE_BUILDDIR.
#
# The traditional way of starting a subdir-configure is running the script
# with ${1+"$@"} but since autoconf 2.60 this is broken. Instead we have
# to rely on eval'ing $ac_configure_args however some old autoconf
# versions do not provide that. To ensure maximum portability of autoconf
# extension macros this helper can be AC_REQUIRE'd so that
# $ac_configure_args will always be present.
#
# Sadly, the traditional "exec $SHELL" of the enable_builddir macros is
# spoiled now and must be replaced by "eval + exit $?".
#
# Example:
#
# AC_DEFUN([AX_ENABLE_SUBDIR],[dnl
# AC_REQUIRE([AX_CONFIGURE_ARGS])dnl
# eval $SHELL $ac_configure_args || exit $?
# ...])
