[ECOS] printf("%d,%ld",a,b); always prints unsigned

Hello,

Under the following conditions:

Target: 
  i386, "net" flavor
eCos:
  2.0 beta with CVS update 2003-05-12
Compiler:
  i386-elf-gcc (GCC) 3.2.1 (eCosCentric)
  under Cygwin on win2K

== The following program:

#include <stdio.h>

int main(void)
{
  int  a = -1;
  long b = -1;
  printf("Should show -1,-1 --> %d,%ld\n",a,b);
}

== has the output:
Should show -1,-1 --> 4294967295,4294967295
==

That's (correctly) 0xFFFFFFFF but it should 
display the signed numbers as "-1".

The interesting parsing is happening in the file:
language/c/libc/stdio/current/src/output/vfnprintf.cxx

Has anyone else seen this?
