Searching for sighander_t is unlikely to succeed anywhere.
The attempt to #include <sys/signal.h> is also not working,
and fixing it shows that doing an AC_DEFINE in the body of
an AC_CHECK_TYPE like that is also risky: both fixed.
(The purpose of this check is opaque to me: neither libcody
nor GCC ever includes <sys/signal.h>, and though <signal.h> is
widely included, it is not directly included by any of the
headers checking this macro... for now I've fixed things
to conform to the comment, but perhaps we should be checking
the non-deprecated <signal.h> instead, and #including it
in mapper-client.h?)

* configure.ac: Fix sighander_t typo and move AC_DEFINE
out of AC_CHECK_TYPE.
* configure: Regenerated.
