*       07-01-87  JCR   made return values conform to ANSI [MSC only]
*       09-24-87  JCR   Added 'const' to declaration [ANSI]
*       11-05-87  JCR   Multi-thread version
*       12-11-87  JCR   Added "_LOAD_DS" to declaration
*       05-18-88  JCR   Error return = EOF
*       05-27-88  PHG   Merged DLL and normal versions
*       06-15-88  JCR   Near reference to _iob[] entries; improve REG variables
*       08-18-89  GJF   Clean up, now specific to OS/2 2.0 (i.e., 386 flat

*       02-15-90  GJF   Fixed copyright
*       03-19-90  GJF   Made calling type _CALLTYPE1, added #include
*                       <cruntime.h> and removed #include <register.h>.
*       03-26-90  GJF   Added #include <string.h>.
*       07-23-90  SBM   Replaced <assertm.h> by <assert.h>
*       10-03-90  GJF   New-style function declarators.
*       04-06-93  SKS   Replace _CRTAPI* with __cdecl
*       01-31-94  CFW   Unicode enable.
*       02-04-94  CFW   Use _putwchar_lk.
*       04-18-94  CFW   Get rid of those pesky warnings.
*       09-06-94  CFW   Replace MTHREAD with _MT.

*int puts(string) - put a string to stdout with newline
*
*Purpose:
*       Write a string to stdout; don't include '\0' but append '\n'.  Uses
*       temporary buffering for efficiency on stdout if unbuffered.
*
*Entry:
*       char *string - string to output
*
*Exit:
*       Good return = 0
*       Error return = EOF
