* Make _Complex_I a proper float _Complex when using GCC 4.2.Ed Schouten2012-01-051-1/+5
| | | | | | | | | | | | | | | | | | | | | 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.

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>. Notes: svn path=/head/; revision=78172
