Subject: Declare raise() for Mac OS X.
X-Git-Url: https://git.ndcode.org/public/gitweb.cgi?a=commitdiff_plain;h=543bbcb9ab02a9195271c524733f24621ee37bf3;p=ack.git

Declare raise() for Mac OS X.

This prevents the warning, "implicit declaration of function raise",
in programs that call raise().  I forgot to declare it because the
function raise() is in libc but the declaration goes in libsys.
