GCC 4.0.1 testsuite uses installed g++ instead of newly bootstrapped g++

["Paul C. Leopardi" <leopardi at bigpond dot net dot au>]

Hi all,
I have recently downloaded, configured, bootstrapped and tested gcc 4.0.1 and 
found the same problem that I reported for gcc 3.4.0 as PR/15356.
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=15356
See also the threads "gcc testsuite apparently can't find g++" 
http://gcc.gnu.org/ml/gcc-help/2004-05/msg00050.html
and "gcc 3.4.0 testsuite gives over 5000 g++ errors"
http://gcc.gnu.org/ml/gcc-help/2004-05/msg00034.html
At that time, as now, the g++ tests invoked via "make -k check" used my 
previously installed g++ rather than the newly bootstrapped g++.
PR/15356 was resolved as WORKSFORME, so I am reluctant to file another bug 
report.

I have checked and re-checked my configuration and the configuration seems OK, 
but the error condition persists.

I have reported this to the suse-amd64 mailing list, thinking that the problem 
may be specific to that architecture.

How do I make the tests find the bootstrapped g++? Shouldn't the test just do 
this automatically? How is the test supposed to find find the bootstrapped 
g++? Is it done via an environment variable? Which environment variable? What 
sets the value of this variable? Is it a script or a program?

What have I configured wrong, if anything? If this really is a bug, then why 
does the test work for Andreas Jaeger and not for me?

Should I file another bug report and hope that I don't kust get WORKSFORME?
Best regards
