Re: [Quantlib-dev] [Quantlib-users] ImpliedQuote() method on BootstrapError<> and Doxygen compilation flag

[Luigi B. <lui...@gm...>]

Hello,
    __DOXYGEN__ is only defined when we're running Doxygen to generate the
documentation that goes at <https://www.quantlib.org/reference/> (for some
reason, it would emit a warning otherwise).  When we actually compile the
code, the method is always included.
