/* iostream.h -- basic stream I/O declarations
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.
