Bug#642053: clang cannot compile C source file successfully if the source includes "errno.h"

[Hong Xu]

Package: clang
Version: 2.7-3
Severity: important

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

   * What led up to the situation?
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
Save the following source code as a C source file:
#include <errno.h>

int main()
{
}

Then compile it:
$ clang tmp.c


   * What was the outcome of this action?
The compilation failed. Error messages are:

In file included from tmp.c:1:
In file included from /usr/include/errno.h:36:
In file included from /usr/include/bits/errno.h:25:
/usr/include/linux/errno.h:4:10: fatal error: 'asm/errno.h' file not found
#include <asm/errno.h>
         ^
1 diagnostic generated.


   * What outcome did you expect instead?

The build should be successful.

Besides, gcc could compile it successfully.
