Hi folks,

i don't know much about variable argument lists, so
i read a few in the Kernighan/Ritchie book.
After that i wrote a little program:

#include <stdarg.h>
#include <stdio.h>

unsigned char fg;

void abc(int anzahl, unsigned char abc, ...)
{
 va_list ap;
 va_start(ap, abc);
 fg = va_arg(ap, unsigned char);
 printf("\n\rErster variabler Parameter: %d", fg);
 va_end(ap);
}

void main(void)
{

 abc((int) 10, (unsigned char) 10, (unsigned char) 51);
}


I haved compiled it on my 80486 DX 2 with djgpp gcc version 2
(operating system OS/2 2.11). 
When i run the program it always prints 0 to stdout.

I also have compiled the program with BORLAND C++ 3.1 and it
works fine. Furthermore the acc compiler on the sun delivered
a result i expected.

I have searched for help in the given web page
http://www.delorie.com/djgpp/mail-archives/djgpp
but i have not found an answer.

Do you know an answer ?

Thanx a lot !!!
