passed tests, so that hostnames recorded in the log file do not
wrongly match.

as ways to alter the configuration, with caveats of each. Move
--program-prefix discussion...

M4sugar requires GNU m4 extensions to be enabled. Override
POSIXLY_CORRECT using -g.
* m4/m4.m4: Unset POSIXLY_CORRECT during first test. Test for -g.
Warn user if he has POSIXLY_CORRECT set but -g is not supported.
* bin/Makefile.am: Substitute @M4_GNU@ into generated files.
* bin/autom4te.in: Pass @M4_GNU@ to m4.
* lib/autotest/general.m4 (at_fn_check_prepare_notrace): Use
$at_trace_echo. Add new REASON argument.
(at_fn_check_prepare_trace): Do not call at_fn_check_prepare_notrace.
Use $at_check_filter_trace.
(at_fn_check_prepare_dynamic): Use at_fn_check_prepare_notrace.
(at_traceon): Initialize to ':'.
(at_traceoff): Remove, use 'set +x' instead throughout.

Initialize them if tracing is requested.
(_AT_DECIDE_TRACEABLE): Adjust call to at_fn_check_prepare_notrace.
This test makes atlocal code use configure tests instead. This
is best practice and could make diagnosing autoconf bugs easier.
