* include/c_global/cmath (pow(float, int), pow(double, int),
pow(long double, int)): Do not define in C++0x mode, per DR 550.
* include/tr1_impl/cmath (pow): Do not bring in unconditionally
from namespace std.
* include/tr1/cmath (pow(double, double), pow(float, float),
pow(long double, long double), pow(_Tp, _Up)): Define.
* include/tr1/complex (pow): Do not bring in from namespace std.
(pow(const std::complex<_Tp>&, int), pow(const std::complex<_Tp>&,
const _Tp&), pow(const _Tp&, const std::complex<_Tp>&),
pow(const std::complex<_Tp>&, const std::complex<_Tp>&)): Define.
* include/tr1_impl/complex (pow(const std::complex<_Tp>&,
const _Up&), pow(const _Tp&, const std::complex<_Up>&),
pow(const std::complex<_Tp>&, const std::complex<_Up>&)): Always
define.
* doc/xml/manual/intro.xml: Add an entry for DR 550.
* testsuite/26_numerics/headers/cmath/dr550.cc: New.
