pdf images ignore bounding box?

[Joshua N Pritikin]

Now that automake generates rules for 'make doc.pdf', I tried it.

The output looks good, except that images seem to be full-page
instead of according to bounding box.  I checked whether the
PDF is matching the EPS:

As you can see, the bounding box looks OK.  It seems like texinfo.tex
is not using the bounding box when in pdf mode.  Is this a bug?
