dnl @synopsis AC_raf_FUNC_WHICH_GETSERVBYNAME_R
dnl
dnl Provides a test to determine the correct way to call
dnl getservbyname_r:
dnl
dnl  - defines HAVE_FUNC_GETSERVBYNAME_R_6 if it needs 6 arguments (e.g linux)
dnl  - defines HAVE_FUNC_GETSERVBYNAME_R_5 if it needs 5 arguments (e.g. solaris)
dnl  - defines HAVE_FUNC_GETSERVBYNAME_R_4 if it needs 4 arguments (e.g. osf/1)
dnl
dnl An example use can be found at
dnl http://raf.org/autoconf/net_getservbyname.c
dnl
dnl Based on Caolan McNamara's gethostbyname_r macro. Based on David
dnl Arnold's autoconf suggestion in the threads faq.
