This means that the code to detect variadic macro support in Boost is duplicated in two places, both in config, which I basically started with the blessing of John Maddock with the BOOST_NO_VARIADIC_MACROS macro, and in Boost PP in a configuration file which I have coded and essentially duplicates the code in config for variadic macro support.
I do not like this. Duplicating functionality in two different places, even as simple as determining variadic macro support for compilers, is error prone and a maintenance problem. Changes in one place have to be done in the other, and this would need to constantly be tracked.
Does it detect the MSVC bug that severely restricts the use of variadic macros with that compiler?
I am aware of a problem with VC++ and variadic macros and already addressed it in my VMD library by finding an effective workaround. The same technique to workaround the VC++ problem is in Boost PP with my work to add variadic macro support for it. If you still find a specific proble with VMD and VC++, please report it to me. The same goes for the work I am doing now to bring variadic macros to Boost PP.
