* 11-06-87 JCR Multi-thread support
* 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
* 09-22-88 GJF Include internal.h to get prototypes for _[s|f]tbuf()
* 02-15-90 GJF Fixed copyright and indents
* 03-19-90 GJF Replaced _LOAD_DS with _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>
* 10-02-90 GJF New-style function declarators.
* 04-06-93 SKS Replace _CRTAPI* with __cdecl
* 09-06-94 CFW Replace MTHREAD with _MT.
* 02-06-94 CFW assert -> _ASSERTE.

*int fputs(string, stream) - write a string to a file

*Purpose:
* Output the given string to the stream, don't write the '\0' or
* supply a '\n'. Uses _stbuf and _ftbuf for efficiency reasons.
*
*Entry:
* char *string - string to write
* FILE *stream - stream to write to.

*Exit:
* Good return = 0
* Error return = EOF
