Actually, that target fails in the same way as 'build' does:

In file included from /mnt/storage/git/libreoffice/sal/cppunittester/cppunittester.cxx:28:0:
/mnt/storage/git/libreoffice/include/cppunittester/protectorfactory.hxx:24:31: fatal error: cppunit/Protector.h: No such file or directory
 #include <cppunit/Protector.h>
                               ^
compilation terminated.

It appears that sal/cppunittester is always built.

Thanks,
Richard
