No, that doesn't compile for me. I saved the above program into test.cc and
compiled with plain vanilla gcc-3.1 on RedHat 6.2, and I got the following

gcc test.cc

from test.cc:1:
/usr/local/include/g++-v3/bits/basic_file.h:52: parse error before `{' token

This is a known problem, caused by installing a new release over an older
release, see http://gcc.gnu.org/onlinedocs/libstdc++/faq/index.html#4_0

The problem is that an older version of basic_file.h is being found, and
it isn't compatible with the new filebuf classes.

Thanks for pointing that out. I thought I was doing good to find the documentation on the
new stdio_filebuf class. Simply deleting /usr/local/include/g++-v3 from 3.0.* before
installing 3.1 solves the problem.
