Always use "make -k check".  Some testsuites exit with an error if one 
or more tests failed, and because this is the normal situation for 
almost all testsuites, this means the only way to get meaningful results 
is to use -k.

You will still get a failure for the fixincludes testsuite, but it will 
be ignored, and the other testsuites will work.

Or alternatively, run the ones you care about individually, e.g. "make 
check-target-libstdc++-v3" which will run only the libstdc++-v3 
testsuite.  Or alternatively, you can cd into the directories you care 
about, e.g. "cd gcc; make check-g++" which will run just the gcc C++ 
testsuite.  Etc.
