Created attachment 27623
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=27623
patch for ctype_base.h

The fix for PR 47045 pollutes the global namespace:

#include <locale>

int main()
{
  int NetBSD = 1;
}

r.cc: In function 'int main()':
r.cc:5:7: error: expected unqualified-id before numeric constant

I received the attached patch from Jörg Sonnenberger, a NetBSD toolchain
developer, and intend to commit it. This PR is to record the regression.
