syscall and smbwrapper on AIX

[Kenneth Stephen]

Hi,

	Faced with the desperate need to get smbwrapper running on AIX, I
made an attempt to port it. I stopped when I realized that the syscall
interface required by the code (realcalls.*) was just not present on AIX.
All the AIX experts that I asked (I work at IBM Austin, and I was able to
ask the AIX architects) said that there is no 'syscall' call on AIX that
will provide a mapping to the various system calls.

	The alternative that I see is to introduce the following change to
realcalls.h :

#if HAVE_SYS_SYSCALL_H
#include <sys/syscall.h>
#elif HAVE_SYSCALL_H
#include <syscall.h>
#endif


gets changed to  :

#if HAVE_SYS_SYSCALL_H
#include <sys/syscall.h>
#elif HAVE_SYSCALL_H
#include <syscall.h>
#else
#define NO_SYSCALL_H
#endif


... and then later in the file, do a #ifdef NO_SYSCALL to introduce code
that is specific to AIX. This would map the real_* macros to the actual
system call invocation.

	Not having done any porting before, I dont have a clue as to
whether I am being supremely stupid or not. Can someone advise me if I am
on the right track?

TIA,
Kenneth
