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?
