Bug#694770: libc6-dev-s390: can't compile 31-bit programs on s390x due to missing "asm/errno.h"

[Mikulas Patocka <mikulas@twibright.com>]

Package: libc6-dev-s390
Version: 2.13-37
Severity: grave
Justification: renders package unusable

Dear Maintainer,
*** Please consider answering these questions, where appropriate ***

   * What led up to the situation?

I tried to compile 31-bit program on 64-bit s390x system

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

Try to compile a simple program that includes errno.h:

#include <errno.h>
int main(void) { return 0; }

Compile it with this command: gcc-4.7 -m31 errno.c

   * What was the outcome of this action?
In file included from /usr/include/bits/errno.h:25:0,
                 from /usr/include/errno.h:36,
                 from errno.c:1:
/usr/include/linux/errno.h:4:23: fatal error: asm/errno.h: Adresář nebo soubor neexistuje

   * What outcome did you expect instead?

The program should compile.



This bug can be worked around if you do:
# cd /usr/include
# ln -s s390x-linux-gnu s390-linux-gnu
.... then, compiling programs with -m31 works fine.

The directory /usr/include/s390-linux-gnu should be installed by 31-bit 
libc development package libc6-dev-s390.
