Bug#333488: linux-kernel-headers: Include of asm/atomic.h is broken when compiling with g++

[Jerome Vizcaino <vizcaino_jerome@yahoo.fr>]

Package: linux-kernel-headers
Version: 2.6.13+0rc3-1.1
Severity: important

Hi,

Including asm/atomic.h breaks compilation with g++.
The simple example below cannot be compiled using g++ 4, 3.4 or 3.3 and
the error is always the same.

-- CODE START --
#include <asm/atomic.h>

int main()
{
 return 0;
}
-- CODE END --

Trying to compile I get the following errors:

/usr/include/asm/system.h:247: error: expected ‘,’ or ‘...’ before ‘new’
/usr/include/asm/system.h: In function ‘long unsigned int
__cmpxchg(volatile void*, long unsigned int, long unsigned int)’:
/usr/include/asm/system.h:250: error: ‘size’ was not declared in this
scope
/usr/include/asm/system.h:254: error: expected type-specifier before ‘)’
token
/usr/include/asm/system.h:260: error: expected type-specifier before ‘)’
token
/usr/include/asm/system.h:266: error: expected type-specifier before ‘)’
token
/usr/include/asm/processor.h: In function ‘void load_esp0(tss_struct*,
thread_struct*)’:
/usr/include/asm/processor.h:486: error: ‘unlikely’ was not declared in
this scope

The real thing is that, I could get it compiled using earlier versions
of linux-kernel-headers.

The problem in system.h is quite easy to fix as g++ thinks the function
parameter new is recognized as a keyword. Changing it to new_ (and so on
in the function) solves the problem.
As for the definition of unlikely which is found somewhere in
linux/compiler.h but only if __KERNEL__ is defined. Defining this
manually for compilation creates more problems of redefinitions.

What can I do ?

Thanks
