\match is not supported by Frama-C. In addition to the ACSL manual,
which describes the full ACSL language, each version of Frama-C has
some implementation notes (in
$FRAMAC_SHARE/manuals/acsl-implementation.pdf, also available on
http://frama-c.com/download/acsl-implementation-${FRAMAC_VERSION}.pdf)
which says in particular which constructions are not currently
supported.

Note that these implementation notes only cover what is done by the
kernel. Plug-ins may themselves add some further restrictions, which,
at least theoretically, are described in their respective manuals.
