<pre>According to
<a href="http://clang.llvm.org/docs/UsersManual.html#differences-between-various-standard-modes">http://clang.llvm.org/docs/UsersManual.html#differences-between-various-standard-modes</a>:
The supported modes for C are c89, gnu89, c94, c99, gnu99 and various aliases
for those modes. If no -std option is specified, clang defaults to gnu99 mode.
-std=c94 is not accepted but -std=iso9899:199409 is.
