dnl @synopsis ACX_WHICH_GETHOSTBYNAME_R
dnl
dnl Provides a test to determine the correct 
dnl way to call gethostbyname_r
dnl
dnl defines HAVE_FUNC_GETHOSTBYNAME_R_6 if it needs 6 arguments (e.g linux)
dnl defines HAVE_FUNC_GETHOSTBYNAME_R_5 if it needs 5 arguments (e.g. solaris)
dnl defines HAVE_FUNC_GETHOSTBYNAME_R_3 if it needs 3 arguments (e.g. osf/1)
dnl
dnl if used in conjunction in gethostname.c the api demonstrated
dnl in test.c can be used regardless of which gethostbyname_r 
dnl exists. These example files found at
dnl http://www.csn.ul.ie/~caolan/publink/gethostbyname_r
