   It doesn't actually look like a broken patch; the problem is that the
2.4.18-5 version of include/linux/sched.h has a block of code that looks
like:

#if CONFIG_SMP
...
#endif

rather than using 

#ifdef CONFIG_SMP

and we #define CONFIG_SMP to an empty value in
src/config/param.i386_linux24.h (actually in all of the param headers
for all of the linux ports).   Applying the patch below lets me build
successfully for 2.4.18-5.
