 *
 *	int _mri_prt (stream, format [, arg]...)
 *
 *	mri_prt is the low level printf function.  It is called by printf
 *	eprintf, fprintf, and sprintf.
 *	It returns the number of characters output (excluding \0 for
 *	sprintf), or a negative value if an output error was encountered.
 *
 *  written by H. Yuen  12/12/86
 *
 *  07/01/88 HY - added %i, %p, %n formats; h, L modifiers; +,space flags
 *  08/16/89 jpc - added mrilib.h to aid in building 68k '881 versions
 *  09/22/89 jpc - split from G32 printf function.
 *		   12 -> sizeof (long double) when incrementing arg
 *  12/18/89 jpc - Removed _cgd routine.  Complete long double conversion
 *		   has to be added when compiler supports this.
 *		   Removed the use of "arg" as "char *".  Now uses ANSI
 *		   "va_arg" method of handling variable arguments.
 *  02/13/90 jpc - modified to print alternate forms.  Calling convention
 *		   of ftoa modified.
 *  05/09/90 jpc - calls _ftoa and _ltoa instead of ftoa and ltoa, respectively
 *  06/07/90 jpc - Leading zeros were dropped if # alternate form was used.
 *  06/14/90 jpc - modified to not bring in output routines when only sprintf
 *		   is called.  Address of putc or equiv. passed in as arg.
 *		   Also, for efficiency, as many post-inc and post-dec 
 *		   expressions as reasonably possible were removed.
 *		   #include's for stdio and mriext were removed to eliminate
 *		   reference to _iob.
 *		   reference to BUFSIZ now hard coded as 512
 *  04/04/91 jpc - ltostr -> _ltostr for ANSI compliance
 *  07/19/91 HY  - added #if for creating a subset version
 *  07/25/91 jpc - s -> str
 *		   Modify size of "buf" to reduce stack demands.
 *  11/10/93 jpc - fixed problem w. prec_flag; it was not getting reset
 *		   correctly.
