My recent exp patch introduced warnings about implicit __isinf declarations in exp because e_exp.c didn't include <math.h>. This patch fixes this. Because <math.h> can't be included after <math_private.h> (because of macro definitions of __nan*), it was necessary to put an include in sysdeps/x86_64/fpu/multiarch/e_exp.c as well. Tested x86_64. * sysdeps/ieee754/dbl-64/e_exp.c: Include <math.h>. * sysdeps/x86_64/fpu/multiarch/e_exp.c [HAVE_FMA4_SUPPORT || HAVE_AVX_SUPPORT]: Likewise.
