compiling scsh on linux 2.0.34

[Immanuel Litzroth <Immanuel.Litzroth@pandora.be>]

To compile scsh on linux 2.0.34 I had to change the macros
in machine/sigset.h to

____File sigset.h________

/* Convert between a lo24/hi integer-pair bitset and a sigset_t value.
** These macros are OS-dependent, and must be defined per-OS.
*/

#define make_sigset(maskp, hi, lo) ((maskp)->__val[0]=((hi)<<24)|(lo))

/* Not a procedure: */
#define split_sigset(mask, hip, lop) \
        ((*(hip)=((mask).__val[0]>>24)&0xff), \
         (*(lop)=((mask).__val[0]&0xffffff)))

_____File sigset.h________

I only have a foggy idea of what I actually did so I cannot answer any 
questions about it.
