Well, I think the problem is with libstdc++ and not newlib. Correctly
nailing C89, C99, and the GNU extensions into namespaces has proven to
be difficult. I think there is no reason for newlib to alter includes
for this case based on __cplusplus.

Instead, this should probably be fixed in the C++ library.

This is incorrect for GNU C++ post 3.0.x, as _GNU_SOURCE is defined in
CPLUSPLUS_CPP_SPEC.

This is currently a low-to-medium priority issue.
