Added skeleton <complex.h> (aligned with the POSIX.1-200x), mostly to fix the "-nostdinc WARNS=X" breakage caused by broken prototypes for cabs() and cabsl() in <math.h>. Reimplemented cabs() and cabsl() using new complex numbers types and moved prototypes from <math.h> to <complex.h>.

Add c{cos,sin,tan}{,h}{,f} functions. This is joint work with bde and kargl.

#define _COMPLEX_H
Added skeleton <complex.h> (aligned with the POSIX.1-200x), mostly to fix the "-nostdinc WARNS=X" breakage caused by broken prototypes for cabs() and cabsl() in <math.h>. Reimplemented cabs() and cabsl() using new complex numbers types and moved prototypes from <math.h> to <complex.h>.

Make _Complex_I a proper float _Complex when using GCC 4.2. It turns out our GCC has quite an interesting bug: typeof(1.0fi) != float _Complex typeof((float _Complex)1.0fi) != float _Complex typeof((float _Complex)1.0i) == float _Complex In other words: if casting to an equal size, GCC seems to take a shortcut. By casting down from a double to a float, GCC doesn't take this shortcut, yielding the proper type. To prevent foot-shooting, add a _Static_assert() to guarantee that _Complex_I is always a float _Complex. I'm not going to MFC this part of the diff. MFC after: 2 weeks
