Oops, this patch was not sufficient. With gcc 13.1.0 I see this warning:

diffseq.h:561:20: warning: 'part.xmid' may be used uninitialized 
[-Wmaybe-uninitialized]

This patch fixes it.

        diffseq: Silence another gcc warning.
        * lib/diffseq.h (compareseq): Move into the scope of the '#pragma GCC
        diagnostic'.
