When running autoreconf with ax_check_sign.m4, autoconf 2.71 complains about the use of AX_TRY_COMPILE. This output comes from an autoreconf of PowerDNS:

libtoolize: copying file 'm4/lt~obsolete.m4' warning: The macro `AC_TRY_COMPILE' is obsolete. You should run autoupdate.
./lib/autoconf/general.m4:2847: AC_TRY_COMPILE is expanded from...

m4/pdns_check_time_t.m4:1: PDNS_CHECK_TIME_T is expanded from... the top level

The attached patch updates the macro to use AC_COMPILE_IFELSE, which has been present in autoconf since at least version 2.60, released in 26 Jun 2006 (I did not check any older releases).
