Again, this is a C11 feature. It is supported by clang, gcc and MSVC.

To clarify this a bit: they permit anonymous unions in C89 and C99 code (meaning you do not need to pass flags like -std=c11 to enable it).

What's the status on compiler requirements? Are they, or will they be, higher? I'm going to take advantage of variadic macros (__VA_ARGS__) for better code generation with the parameter parsing implementation I'm finishing up, and it would be nice to not have to make two versions with a compiler check. e.g. for MSVC or GCC >= 3, but I don't know what else...

For 7.0, we are gonna focus on MSVC 2015 (VC14), although VC11 is also known to work, we will do the 7.0+ releases with VC14 (that is releasing later this month)

Right, but MSVC isn't a concern for the variadic macros thing I'm talking about (supported since 2005). [1] I'm just wondering about the subject of this old thread: have we bumped, or will we, the minimum requirements for *ALL the other compilers* PHP "supports?" e.g. requiring some or all of C99 support? That would hopefully say whether we can rely on variadic macros. :-) Thanks, Matt [1] https://en.wikipedia.org/wiki/Variadic_macro
