Arch Linux

Description:

gcc 4.6.0-5 not finish compile a vanilla kernel with steps:

make menuconfig (previous .config from slackware 13.37 with gcc 4.5.2 and work fine)
make bzImage - Fail at finish time with various errors

I see an error in debian bug list, and the _same_ error i can reproduce in x86 and x86_64 system ArchLinux (have 1 notebook and 1 desktop)

Test it:

test.c:
----------------------------------------------------------
#include <stdio.h>

int main(void)
{
int x;
x = printf("hello, world\n");
return 0;
}
-----------------------------------------------------------
gcc -Wall -Werror test.c; echo $?

test.c: En la función ‘main’:
test.c:5:13: error: se define la variable ‘x’ pero no se usa [-Werror=unused-but-set-variable]
cc1: todos los avisos se tratan como errores

------------------------------------------------------------

gcc -Werror=unused-but-set-variable test.c; echo $?

test.c: En la función ‘main’:
test.c:5:13: error: se define la variable ‘x’ pero no se usa [-Werror=unused-but-set-variable]

The same problem is reported in debian, reference:

http://lists.debian.org/debian-gcc/2011/02/msg00107.html


Additional info:
* package version(s)
* config and/or log files etc.
System up to date, archlinux_x86 stable and archlinux_x86_64 stable, the same error. Using xfce or kde in both machines.

note: if you need me to translate the texts in Spanish just ask him
