# Notes:

#  We don't import copysign finite, fpclassify, isinf, isnan, and signbit
#  since our own versions are nicer and just as correct and fast (except
#  perhaps that they don't handle non-finite arguments well?).
#
#  Also, leave out cabs for now since it doesn't seem overridable in
#  glibc.
