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.
