This indicates you are either doing something wrong or your C library
is severely messed up.

/usr/include/string.h is part of the C library, and the type
__locale_t should be defined by another header in the C library,
/usr/include/xlocale.h

No, that should work fine (and it does, I use such a setup frequently).

I suggest you stop adding anything to C_INCLUDE_PATH. If you just
invoke gcc 4.8.1 it should know how to find all the standard C and C++
headers it needs, without your help.

If that still doesn't work and you want further help you will need to
show the exact gcc or g++ command that causes the error, as well as
any environment variables such as C_INCLUDE_PATH and CXX that you
might have set that would confuse things. We can't guess what the
problem is if you don't tell us exactly what you're doing.
