stdarg.h support seems to be fine (btw, can we have some backwards 
compatibility here with __va_copy for 1 major release?), no failures with 
my testcases.

varargs.h doesn't quite work it seems. First, the final #endif is missing 
in varargs.h. Then the following 3 testcases fail:

- va-arg-3.c out of the testsuite

- varargs10.c:
#include <varargs.h>

inline void debug(i1, i2, i3, i4, i5, i6, i7, f1, f2, f3, f4, f5, f6, f7, 
f8, f9, va_alist)
   int i1, i2, i3, i4, i5, i6, i7;
   double f1, f2, f3, f4, f5, f6, f7, f8, f9;
   va_dcl
{
   va_list ap;

   va_start(ap);

   if ( va_arg(ap,int) != 8)
     abort();
   if ( va_arg(ap,int) != 9)
     abort();
   if ( va_arg(ap,int) != 10)
     abort();
   va_end( ap );
}

int main(void)
{
      debug(1, 2, 3, 4, 5, 6, 7, 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 
9.0, 8, 9, 10);
      exit(0);
}


- varargs11.c:
#include <varargs.h>

typedef long long int INT64;

inline void debug(i1, i2, i3, i4, i5, i6, i7, i8, i9, va_alist)
   int i1, i2, i3, i4, i5, i6, i7, i8, i9;
   va_dcl
{
   va_list ap;

   va_start(ap);

   if ( va_arg(ap,int) != 10)
     abort();
   if ( va_arg(ap,INT64) != 0x123400005678LL)
     abort();
   va_end( ap );
}

int main(void)
{
      debug(1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 0x123400005678LL);
      exit(0);
}


I haven't looked into the failures further yet, but I have the impression 
it's only one common problem. Unless the fix is obvious to you, I'll debug 
it later today.
