dnl AC_SNPRINTFV_CONVENIENCE[(dir)] - sets LIBSNPRINTFV to the link flags for
dnl the snprintfv convenience library and INCSNPRINTFV to the include flags for
dnl the snprintfv header and adds --enable-snprintfv-convenience to the
dnl configure arguments. Note that AC_CONFIG_SUBDIRS is not called. If DIR
dnl is not provided, it is assumed to be `snprintfv'. LIBSNPRINTFV will be
dnl prefixed with '${top_builddir}/' and INCSNPRINTFV will be prefixed with
dnl '${top_srcdir}/' (note the single quotes!). If your package is not
dnl flat and you're not using automake, define top_builddir and
dnl top_srcdir appropriately in the Makefiles.
