Depends what you mean by portable.
You can't take the output of the gcc llvm frontend on one platform, and
run it on another, like cfront could.

The sizes, alignments, etc, of things will be different, where people
use sizeof(x), etc, in their code.


Unless you hacked up the C frontend to give you sizeof_expr, etc.
