Various type-generic libm wrapper templates, as used for float128, set errno but do not include errno.h. I presume they must get an implicit include from some internal header on powerpc64le; they don't get such an implicit include on x86_64. This patch adds the missing includes of errno.h to each such wrapper. Tested for x86_64 (in conjunction with float128 patches). * math/w_acos_template.c [__USE_WRAPPER_TEMPLATE]: Include <errno.h>. * math/w_acosh_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_asin_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_atanh_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_cosh_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_exp10_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_exp2_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_exp_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_fmod_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_hypot_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_j0_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_j1_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_jn_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_lgamma_r_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_lgamma_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_log10_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_log2_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_log_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_pow_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_remainder_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_sinh_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_sqrt_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_tgamma_template.c [__USE_WRAPPER_TEMPLATE]: Likewise.
