<varargs.h> for Turbo C ?

[Steve Harrold]

Re: <varargs.h> vs <stdarg.h>

Even though the <stdarg.h> file has definitions for "va_start", "va_arg",
and so on, these definitions are not the same as found in the <varargs.h>
file.

	#include <varargs.h>		#include <stdarg.h>
	void va_start(argptr) ;		void va_start(argptr,prevparam) ;
	type va_arg(argptr,type) ;	type va_arg(argptr,type) ;
	void va_end(argptr) ;		void va_end(argptr) ;
	va_alist			va_list argptr;
	va_dcl

	type function(va_alist)		type function(param)
	va_dcl /* no semicolon */       type param ;
	{...code...}			{...code...}

Even though the files are short, the #defines are rather convoluted, 
rather reminiscent of APL style coding.  

Rather than spend the time to study how stacks are created and manipulated 
by the Turbo C compiler and then to produce a reliable "port" of Turbo C's
<stdarg.h> file to <varargs.h> (including the labor of creating test
cases), I've always resorted to dropping Turbo C for Microsoft C whenever
I handle source code that uses <varargs.h>.

I'm still hopeful that some kind soul will step forward with a solution.
