Forgot to consider libtest33-v{0,1}.so in test-diff-suppr.cc
    
    I forgot the make test-diff-suppr.cc run over libtest33-v{0,1}.so even
    though this test was added to the source distribution.  Fixed thus.
    
    	* tests/data/test-diff-suppr/test33-report-0.txt: New refernce report.
    	* tests/test-diff-suppr.cc (in_out_specs): Compare libtest33-v0.so
    	and libtest33-v1.so.
