Update.
2001-03-12 Ulrich Drepper <drepper@redhat.com> * sysdeps/ieee754/dbl-64/e_remainder.c: Fix handling of boundary conditions. * sysdeps/ieee754/dbl-64/e_pow.c: Fix handling of boundary conditions. * sysdeps/ieee754/dbl-64/s_sin.c (__sin): Handle Inf and NaN correctly. (__cos): Likewise. * sysdeps/ieee754/dbl-64/e_asin.c (__ieee754_asin): Handle NaN correctly. (__ieee754_acos): Likewise. redefinition. * sysdeps/ieee754/dbl-64/endian.h: Define also one of BIG_ENDI and LITTLE_ENDI. * sysdeps/ieee754/dbl-64/MathLib.h (Init_Lib): Use void as parameter list.
