Sorry, I found the solution... this worked for me too.

Hi,
I had the exactly same problem compiling
pwc-10.0.12-rc1 with kernel 2.6.8-24.
I did not spent much time to investigate this problem.
The error message
tells what to do..
...
/home/pete/pwc-10.0.12-rc1/pwc-ioctl.h:60: error:
redefinition of typedef
'__le16'
include/linux/types.h:149: error: previous declaration
of '__le16' was here
...
If it is previously defined I don´t need it in
pwc-ioctl.h,
I fixed it for me this way ;-)
...
#if LINUX_VERSION_CODE <= KERNEL_VERSION(2, 6, 10)
/* Compatibility for older kernel
typedef __u16 __le16;
*/
#endif
...
Hope this helps.
Werner
