I think I should do this:

* make bp-sym.h a gcc-specific header, since it's gcc that defines
  how BP symbols are mangled.
* for libc, guard inclusion of bp-sym.h with `#if__BOUNDED_POINTERS__'
  and define it to just return its arg otherwise.
* Since gcc expands pragmas, it will know if a symbol is BP or not, so
  we needn't pre-mangle the name.

A patch will follow later today.
