 * functioning stderr that it makes sense to write to) and not in
 * GUI applications (which don't).
 * 
 * FLAG_INTERACTIVE is set when a full interactive shell session is
 * being run, _either_ because no remote command has been provided
 * _or_ because the application is GUI and can't run non-
 * interactively.
 * 
 * These flags describe the type of _application_ - they wouldn't
 * vary between individual sessions - and so it's OK to have this
 * variable be GLOBAL.
 * 
 * Note that additional flags may be defined in platform-specific
 * headers. It's probably best if those ones start from 0x1000, to
