(BTW, just in case anyone is wondering now: the above rule is not
suitable for use in Automake because it can be severely suboptimal
if, say, only a couple of objects are built in the current directory
but there is a huge build directory tree which find would traverse.)

Nope, sorry.

We have a bug tracker.  Just write to the bug-automake list.
This is documented at
http://www.gnu.org/software/automake/manual/html_node/Reporting-Bugs.html
which is linked from the Automake home page
