Zitat von Edward Diener <eldiener@tropicsoft.com>:
What is the boost macro which can be used to determine whether or not a compiler supports variadic macros ? I looked at the config macros but could not find the necessary macro documented there.
there is none to my knowledge.
If there is none, then obviously Boost code can not currently use variadic macros for anything.
if one is being added, please also take this MSVC bug into account: https://connect.microsoft.com/VisualStudio/feedback/details/521844/variadic-...
Welcome to the world of "Unfortunately it does not meet the triage bar for the current release of Visual C++". It's the standard reply in my own experience. No wonder Boost does not worry about using variadic macros yet.
someone there has submitted a workaround for this bug. I've tried it, it looks sufficient to implement macros like BOOST_PP_TUPLE_*, but variadic, without the "size" parameter for MSVC (and C99/C++0x)
