Bug in va_list/va_arg on PowerPC

[Stephane Bortzmeyer]

bortzmeyer@yoko:~/tmp$   gcc -c test-va.c
test-va.c: In function `main':
test-va.c:7: incompatible types in assignment

bortzmeyer@yoko:~/tmp$   cat test-va.c 
#include <stdarg.h> 

int main () {

  va_list values;
  va_list args;
  values = va_arg(args,va_list);

}

[Output of gcc -E attached.]

The same code compiles fine on an i386, same version of gcc, same OS, and on 
an Alpha, same version of gcc, Tru64 OS.


[The actual code - the Java Virtual Machine kaffe - is much longer.]



The test machine is a Macintosh PowerPC G4 (PowerBook)
