FW: iostream implementaion incomplete

[Shiv Shankar Ramakrishnan]

|You are right that it's non-standard, but libstdc++-2 supported it.

You can get a similar affect (in a way) by enabling exceptions so that
an exception is thrown when a file doesn't exist. So you could then
immediately catch it and do something else. I don't know whether this
would suffice in your case though.
One caveat though - it might even be risky to do this if the code isn't
exception safe.

Thanks,
