Darn, this looks like a regression of 1.10 over 1.9.6, due to the
  sed 10q

in m4/depout.m4: because cppunit.mk is longer than 10 lines, it won't
get to the "generated by automake" line any more.

Here's a hacky workaround: insert a comment like this near the top of
cppunit.mk (and do not use it for non-automake substituted files,
otherwise you need another file, am-fake.mk or so):
  # do not remove the following line, it helps Automake 1.10
  # generated by automake.

Phew.  Do things work then?  Could you also try the Automake patch
below?

OK to apply this to Automake to fix the failure?

Cheers, and thanks,
Ralf

        * m4/depout.m4 (_AM_OUTPUT_DEPENDENCY_COMMANDS): Again search
        the whole file, but use sed to reduce the line length.
        Fixes 1.10 regression.  Report by David Byron.
        * THANKS: Update.
