Author: ed Date: Sat May 25 18:55:55 2013 New Revision: 250990 URL: http://svnweb.freebsd.org/changeset/base/250990 Log: Add C11 macros CMPLX(), CMPLXF() and CMPLXL(). Clang allows us to initialize complex numbers using an array initializer, casted to a complex type. GCC has a builtin called __builtin_complex().
