In C, _B would be in implementation namespace, and thus attempting to
use it for a user variable is liable to produce, um, arbitrary
surprises.

I don't know whether there's a C++ standard or not, and if there is
whether it specifies anything similar.  If so, this is programmer
error; if not, it's arguably a bug in the C++ <string> include -
probably due to including ctype.h, with its _B, _P, etc, macros.
