# languages
all (full distribution)

# sytem info
Solaris 2.6 (with recent patches) on Sun Ultra-1;
the produced binary installation is also successfully used
on Sparcstation-4 (Solaris 2.6), which is why -msupersparc was used,
and also to be used on Ultra-10 (Solaris 2.7/8)

# other info
in contrast to earlier versions (including gcc-3.0.4), everything
and all languages built fine even using non-standard options
for the bootstrap:
    -fPIC -O3 -funroll-loops -msupersparc -Qn -Wa,-Qn -s
However, the testsuite results (submitted using the script)
deviate slightly from the ones reported for Solaris2.6
(presumably bootstrapped with more standard options).
***** Why do the compiler flags used for the bootstrap *****
***** do not get reported with gcc -v, and are also    *****
***** not required for reporting?                      *****
(it seems to make a difference, even regarding to the success
of the bootstrap, resp. of the stage2/3 comparison, which failed
with gcc-3.0.4 with the above flags...)
