OK, it has effect, :-)

And pass gcc testsuite. The related result is below:

[root@localhost contrib]# ./compare_tests ../../build-gcc-cur
../../build-gcc-cur-new
# Comparing directories
## Dir1=../../build-gcc-cur: 2 sum files
## Dir2=../../build-gcc-cur-new: 2 sum files

# Comparing 2 common sum files
## /bin/sh ./compare_tests  /tmp/gxx-sum1.1535 /tmp/gxx-sum2.1535

Old tests that failed, that have disappeared: (Eeek!)
