    There are some inline functions here which generate a LOT of code
    (as much as 300 bytes), but are available inline because AT&T did
    it that way.  We have also made them true functions in the library
    and conditionally deleted the inline code from this header.

    If you really want these big functions to be inline, #define the
    macro name _BIG_INLINE_ before including this header.

    Programs will compile and link correctly even if some modules are
    compiled with _BIG_INLINE_ and some are not.
