commit 5878dd9d53a00fa28800236d79e38e55f85fc98d
Author: Joseph Myers <joseph@codesourcery.com>

    Use C11 CMPLX* macros in libm tests.
    
    libm-test.inc has a macro BUILD_COMPLEX to construct a complex number
    with given real and imaginary parts while allowing properly for signed
    zeroes, infinities and NaNs (which don't work properly with a simple
    real + I * imag, in the absence of compiler support for imaginary
    types), using assignment to __real__ and __imag__ parts of the number.
    C11 defines CMPLX* macros for this purpose, which GCC 4.7 and above
    provide suitable built-in functions for.  This patch redefines
    BUILD_COMPLEX in terms of the standard macros.
    
    Tested for x86_64 and x86.
    
    	* math/libm-test.inc (BUILD_COMPLEX): Remove macro.
    	* math/test-double.h (BUILD_COMPLEX): New macro.
    	* math/test-float.h (BUILD_COMPLEX): Likewise.
    	* math/test-ldouble.h (BUILD_COMPLEX): Likewise.
