Vadim Zeitlin 00960b40b9 Replace obsolete AC_TRY_XXX macros with AC_XXX_IFELSE
No real changes, just avoid warnings from autoconf 2.71 when
regenerating configure.

Note that double brackets must be used around any code using brackets to
preserve them during the expansion.

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.
