Problem with __sys_siglist test under Tru64

[Tony Leneis]

        I noticed when building coreutils-5.2.0.tar.gz that configure
doesn't recognize __sys_siglist[] on Tru64 systems.  The problem is the
test program doesn't include signal.h.  One could imagine that the tests
for _sys_siglist[] and sys_siglist[] might also require signal.h to be
included...  (It makes sense that the array would be declared there.)
Anyway, here's the patch to configure for the __sys_siglist[] test:

--- configure.orig      2004-02-08 12:13:01.000000000 -0800
+++ configure   2004-02-27 19:23:21.000000000 -0800

(i.e. just add "#include <signal.h>" to the __sys_siglist check program.)
