I think you're right.

I assumed it was not standard because per 
https://gcc.gnu.org/onlinedocs/gcc/Variable-Length.html GCC variable 
length array supports goes beyond C99 specs, and MSVC 2013 supposedly 
supports C99, but per 
http://blogs.msdn.com/b/vcblog/archive/2013/07/19/c99-library-support-in-visual-studio-2013.aspx 
this is *library*, not full syntax support.

No, unfortunately that's too restrictive.  MSVC supports a few things 
beyond C89, so -std=c98/-pendantic ends up complaining about a bunch 
things that we use and are supported everywhere.
