Replace obsolete autoconf macros with their modern replacements.
AC_TRY_COMPILE(...) -> AC_COMPILE_IFELSE([AC_LANG_PROGRAM(...)])AC_TRY_LINK(...) -> AC_LINK_IFELSE([AC_LANG_PROGRAM(...)])AC_TRY_RUN(...) -> AC_RUN_IFELSE([AC_LANG_PROGRAM(...)])AC_LANG_SAVE/RESTORE -> AC_LANG_PUSH/POPAC_DECL_SYS_SIGLIST -> AC_CHECK_DECLS(...) (per snippet in autoconf manual)Also use AC_LANG_SOURCE instead of AC_LANG_PROGRAM, where the main()function is not needed.With these changes, autoconf -Wall doesn't complain anymore.Andreas Karlsson
