# 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.
