Comment (by andysem):

 This is a compiler bug, the sentry class defined by STL must be
 convertible to bool (which makes basic_formatting_ostream<>::sentry
 convertible as well). Please, report it to the compiler vendor.

 As for the workaround, I don't have this compiler to test it. I'd
 appreciate if you could provide a patch. I can suggest two possible
 avenues of experimenting:

 1. Change all conditional expressions involving sentry to double negative
 forms. E.g. change "if (guard)" to "if (!!guard)".

 2. Add operator!() and BOOST_EXPLICIT_OPERATOR_BOOL() to
 basic_formatting_ostream<>::sentry definition.
