Revisiting this mail; I'm pushing the following patch (plus a change to
the THANKS file, not shown here, to make life harder for spam harvesters):

Subject: [PATCH] AC_PROG_CC: also try $CC -version, for cl6x compiler
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Anaïs Bouque reported that the cl6x compiler only understands -version:

* c.m4 (AC_PROG_CC): Add another version probe.
* THANKS: Update.
