13.5.4 AM_GNU_GETTEXT_INTL_SUBDIR in intldir.m4

The AM_GNU_GETTEXT_INTL_SUBDIR macro specifies that the AM_GNU_GETTEXT macro, although invoked with the first argument ‘external’, should also prepare for building the intl/ subdirectory.

The AM_GNU_GETTEXT_INTL_SUBDIR invocation can occur before or after the AM_GNU_GETTEXT invocation; the order doesn’t matter.

The use of this macro requires GNU automake 1.10 or newer and GNU autoconf 2.61 or newer.
