Some packages seem to require  a macro file  named  "cppunit.m4" to be
installed at the following location:

      $PRODTREE/actools/share/aclocal/cppunit.m4

where $PRODTREE/actools is an absolute path for the  "actools" instal-
lation directory.

"cppunit.m4" seems to have originated with a Sourceforge package named
"cppunit", but as of 2006, the latest version of that package is about
four years old,  and newer versions  of  "cppunit.m4" are circulating.
It's not  clear where  the correct version of "cppunit.m4" is supposed
to come from.

This directory contains:

      cppunit.m4     - Obtained from:
      http://cvs.sourceforge.net/viewcvs.py/*checkout*/cppunit/\
cppunit/cppunit.m4?rev=1.9
