You would probably want to check for permission to write to the
specified file, so you don't lose your stderr if the open fails.
I I recall correctly, freopen will close the given descriptor
before attempting the open, so if the open fails you've lost
your stderr and any code that writes to it (such as all the debugging
you have scattered through the whole source base) will cause
a possibly fatal error.
