Try to avoid breaking its double use (only works on a little-endian

32-bit machine such as the i386 anyway).

Use __KERNEL__ when you're about to use kernel functions,
|
||
|
|
(which you should not do here anyway, since this file is
|
||
|
|
used by glibc).
|
||
|
|
Use defined(__KERNEL__) || defined(__elinux__) when doing
|
||
|
|
things that only makes sense on an elinux system.
|
||
|
|
Use __CRIS__ when you're about to do (really) CRIS-specific code.
