fix definition of CMPLX macros in complex.h to work in constant expressions
based on patches by Jens Gustedt. these macros need to be usable in static initializers, and the old definitions were not. there is no portable way to provide correct definitions for these macros unless the compiler supports pure imaginary types. a portable definition is provided for this case even though there are presently no compilers that can use it. gcc and compatible compilers provide a builtin function that can be used, but clang fails to support this and instead requires a construct which is a constraint violation and which is only a constant expression as a clang-specific extension. since these macros are a namespace violation in pre-C11 profiles, and since no known pre-C11 compilers provide any way to define them correctly anyway, the definitions have been made conditional on C11.
