[Midnightbsd-cvs] src: complex.h: work around a GCC 4.2 bug.

[laffer1 at midnightbsd.org]

Log Message:
-----------
work around a GCC 4.2 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.

Obtained from: FreeBSD
