Author: ed Date: Thu Feb 9 15:28:28 2012 New Revision: 231282 URL: http://svn.freebsd.org/changeset/base/231282 Log: MFC r229590 manually: 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.
