What is a successful build?

[Stephen L Moshier <steve at moshier dot net>]

According to

  http://gcc.gnu.org/gcc-3.0/buildstat.html

gcc-3.0.4 builds successfully on various computers, but the
regression test results are not discussed very much.

For example,

  http://gcc.gnu.org/ml/gcc/2002-02/msg01345.html

says it builds on sparc-sun-solaris2.7 but the message does not mention
the 450 unexpected libjava failures and other testsuite failures that
happened when I tried to build it.  The documentation does not seem to
mention anything special about java on this computer system, and four
different choices of configuration options gave substantially
identical results.  Are these regressions well known?  Are these
problems documented somewhere?  Is this really a success?
