Hi!
These two changes were necessary to compile libstdc++-v3 against glibc
2.1.91 headers. The latter one is needed because that library is being
compiled with -Werror.

* math/bits/cmathcalls.h (cimag): Add __THROW.
(creal, conj): Likewise.
* wctype/wctype.h (_ISwbit): Avoid warnings about shifting left
by negative value.
