Failure in test silent5.test with heirloom make

[Stefano Lattarini]

Hello automakers.

I encounterd the following failure when trying out the Automake 
testsuite using Heirloom make as $MAKE:
  
  $ /opt/heirloom/bin/make --version
  make: illegal option -- v
  usage: make [-f makefile] [-p] [-i] [-k] [-s] [-r] [-n] [-u]
            [-b] [-e] [-t] [-q] [names]
  $ strings /opt/heirloom/bin/make | grep '@(#)'
  @(#)make.sl     1.40 (gritter) 3/15/07
  $ cd ~/src/automake/tests
  $ MAKE=/opt/heirloom/bin/make /bin/bash ./silent5.test >x.log 2>&1
  $ echo $?
  1

The failure is not spurious, and seems due to the fact that heirloom 
make is overly verbose in rules involving `flex' even when silent-rules 
are enabled.

The full log of the test run is attached.  Let me know if you need 
more information.

Regards,
    Stefano
