Description: Linux system headers
jakub, thanks for re-assigning :)
The problem is actually with linux-headers; <linux/wait.h> is not
C++-compatible. It relies on implicit conversions from void * to unsigned long
*. Simple test program:
#include <linux/wait.h>
int main() {}
:)
The obvious patch, modifying wait.h to make these conversions explicit, works
fine, but modifying the argument types may be a better way to go, I don't know.
By the way, apparently g++ has a switch to make this a warning instead of an
error (-fpermissive), so I made le use this and it should compile now, but it
would still be great if this is not necessary.

Unfortunately that won't work since different archs have different function
prototypes for test_bit and test_and_set_bit. This is fixed in the 2.6.15
headers; attaching a patch for the 2.6.11 headers.
