A *very* weak confidence, and a roundabout way of doing it at
that!  I just want to raise a concern: I hope it isn't policy.

(I like test-suites, and ones exercising existing-code coverage,
functional coverage and fixed bugs is a minimum.  I could
rewrite the whole thing and not worry -- except of course to
check that the new code paths are covered!)  Besides, i960 is
obsoleted, removed from gcc, so no hope in current CVS for that.

So they all say. :-)  I'd be most thankful to get that SID issue
resolved.  What are y'all using for CGEN debugging?  I tried
psd-1.2.1 but it doesn't seem guile-compatible.
