  We choose implementation as follows:
  ------------------------------------
  On Windows using Visual C++ the native implementation should be
  preferrable. When using gcc we prefer the Solaris implementation
  before the gcc because of stability preference, we choose gcc
  builtins if available, otherwise we choose the somewhat broken
  native x86 implementation. If neither Visual C++ or gcc we still
  choose the Solaris implementation on Solaris (mainly for SunStudio
  compilers).
