Support C99 Variable Length Arrays

VLAs are turning out to be common these days, making it impossible to build C code developed with other compilers.

    The MSVC team plans to achieve C conformance but we are first very focused on completing our C++ conformance work.

    We have done some C99 conformance work, most notably C99 _Bool, compound literals, C99 designated initializers, and variable declaration a couple of years back. More recently as we've implemented C++ features that resemble C features we have also implemented their C counterparts.

    Lastly, we have started to implement a conforming preprocessor for both C++ and C conformance.

    I can't comment on VLAs specifically, nor on a timeline for C conformance, but we have heard this request. Thank you!

    I guess MS thinks people are too stupid to use VLA's. Would lead to a rise in applications with stack overflow errors. Gotta love the hand holding going on these days.
