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
