           Summary: -std=c94 not an accepted option
           Product: clang
           Version: 3.4
          Hardware: Other

According to
http://clang.llvm.org/docs/UsersManual.html#differences-between-various-standard-modes:
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.
