[Bug libstdc++/15522] slow IO in g++ 3.X.Y

This is already fixed in gcc3.4.0. On my machine (P4-2400), I get,
approximatively (averaging would be needed):

"C++"
0.180u 0.230s 0:00.46 89.1%     0+0k 0+0io 201pf+0w

"C"
0.170u 0.200s 0:00.44 84.0%     0+0k 0+0io 74pf+0w

Thanks for your report, anyway!

P.S. If sync with stdio is not really needed, for best performance consider
calling 'std::ios::sync_with_stdio(false);' before doing any I/O: with 3.3.x
it makes *a lot* of difference.
