Compare the headers, and note that GCC 3.0's C++ I/O library is fully
templatized, as demanded by the C++ Standard, whereas GCC 2.95's was
not.  That's the cause of the slow-down, which is unfortunate, but
probably won't be fixed without pre-compiled headers or exported
templates.  Oh, you may try -fno-implicit-templates; that might help.

Note that cpu=ultrasparc is not fully supported in GCC 3.0.
