Shadow headers would work if libsupc++ was strict about namespaces.
This only possible if g++ maps std::size_t -> size_t. (Hint hint.)
* include/c_std/assert.h: Add guards.
* include/c_std/bits/std_climits.h: Correct typo.
* include/c_std/ctype.h: Remove #error.

* libio/libioP.h: Break up extern "C" bits around includes.
* libio/libio.h: Only include C headers, or else _C_legacy namespaces
will be nested.
* libio/libioP.h: Same here.
