[Bug c/25504] New: -ansi -Wall should warn about variable-size arrays

["giles at xiph dot org" <gcc-bugzilla at gcc dot gnu dot org>]

I generally expect 'gcc -ansi -Wall' to catch non-portable code, but it does
not throw a warning about variable-size arrays.

'gcc -ansi -pedantic' does throw an appropriate warning. However, it appears
that MSVC still doesn't support this feature, and so I think it would be more
appropriate to throw a warning either with '-ansi -Wall' or just with '-ansi'
without requiring -pedantic to reflect the danger using this feature.
