  46    the string to [unsigned] long long conversion routines.

  48    Furthermore, instead of having the prototypes in stdlib.h like
  49    everyone else, they put them into a non-standard header
  50    <inttypes.h>.  Ugh.
  51
  52    <inttypes.h> defines a variety of things, some of which we
  53    probably do not want.  So we don't want to include it here.
  54
  55    Luckily we can just declare strtoll and strtoull with the
  56    __asm extension which effectively renames calls at the
  57    source level without namespace pollution.
  58
  59    Also note that the compiler defines _INCLUDE_LONGLONG for C++
  60    unconditionally, which makes intmax_t and uintmax_t long long
  61    types.
  62
  63    We also force _GLIBCPP_USE_LONG_LONG here so that we don't have
  64    to bastardize configure to deal with this sillyness.  */
