-# SYNOPSIS
-#
-#   AX_FUNC_WHICH_GETHOSTBYNAME_R
-#
-# DESCRIPTION
-#
-#   Determines which historical variant of the gethostbyname_r() call
-#   (taking three, five, or six arguments) is available on the system and
-#   defines one of the following macros accordingly:
-#
-#     HAVE_FUNC_GETHOSTBYNAME_R_6
-#     HAVE_FUNC_GETHOSTBYNAME_R_5
-#     HAVE_FUNC_GETHOSTBYNAME_R_3
-#
-#   as well as
-#
-#     HAVE_GETHOSTBYNAME_R
-#
-#   If used in conjunction with gethostname.c, the API demonstrated in
-#   test.c can be used regardless of which gethostbyname_r() is available.
-#   These example files can be found at
-#   http://www.csn.ul.ie/~caolan/publink/gethostbyname_r
-#
-#   based on David Arnold's autoconf suggestion in the threads faq
-#
-#   Originally named "AC_caolan_FUNC_WHICH_GETHOSTBYNAME_R". Rewritten for
-#   Autoconf 2.5x, and updated for 2.68 by Daniel Richard G.
