atoi is always a bad idea.

If you're writing C, you should use strtol instead. If you're writing C++,
you should use a stringstream instead.

Or use boost lexical_cast, which looks like a cast but works with streams to
do string-number conversions. But any boost library involves lots of
inter-library dependencies, and would surely increase your compilation
times (the compiler has to untangle all the templated mess :P). So just
stick to streams.
