* tgmath_logb.patch implements the missing logb function (see C99 standard 7.22, paragraph 5). * tgmath_fabs_complex.patch corrects the return types for the complex fabs functions. These must be non-complex float/double/long double (see C99 standard 7.22, paragraph 4 and 7.3.8.1). Patch contributed by Kristof Beyls.
