This is required to work according to the C++ standard, so it better
work on an OS with a proprietary libc. However, it will work much less
efficiently.
What will stop working is:
fprintf((FILE*) cout.rdbuf(), "This should be line 1.\n");
I certainly don't see many programs breaking because of this ...
