--- Comment #14 from Alexandre Oliva <aoliva at gcc dot gnu.org> --- Thanks. The other problem the testcase in this PR evidenced was that simd_math.h and simd_scalar.h seem to disregard _GLIBCXX_USE_C99_MATH_TR1, and on newlib-using targets, that don't declare in math.h enough for this macro to be defined, compiling the testcase complains about numerous such functions not being declared in std::.
