Fix clog10 (-0 +/- 0i) (bug 16362).
This patch fixes the imaginary part of clog10 (-0 +/- 0i), which should be +/-pi / log(10) by analogy with clog (the functions were wrongly returning a result with imaginary part +/-pi, same as for clog, and the tests matched the incorrect result, though both functions and tests were correct for the similar case of clog10 (-inf +/- 0i)). Tested x86_64 and x86. [BZ #16362] * math/s_clog10.c (M_PI_LOG10E): New macro. (__clog10): Use M_PI_LOG10E instead of M_PI when real and imaginary parts are 0. * math/s_clog10f.c (M_PI_LOG10Ef): New macro. (__clog10f): Use M_PI_LOG10Ef instead of M_PI when real and imaginary parts are 0. * math/s_clog10l.c (M_PI_LOG10El): New macro. (__clog10l): Use M_PI_LOG10El instead of M_PIl when real and imaginary parts are 0. * math/libm-test.inc (clog10_test_data): Update expected results for when real and imaginary parts are 0.
