I have built gcc 4.6.3 on Redhat 4.3, but it occurred below error
when running testsuite with “make –k check”:
=== libstdc++ Summary ===
# of expected passes 8314
# of unexpected failures 1
# of expected failures 84
# of unsupported tests 113
make64[3]: *** [check-DEJAGNU] Error 1
make64[3]: Leaving directory `/home/linchongzhi/software/objdir_463/

make64[2]: *** [check-am] Error 2
make64[2]: Target `check' not remade because of errors.
This is normal; it's why you use -k.
