Actually I prefer (d) [hands up everyone who's surprised?  :-)]  I
don't see why we should implement syscall in assembler.  After all, that
would be the third implementation :-)  Why not have something along the
lines of:

int syscall(int nr, int arg1, int arg, int arg3, int arg4, int arg5, int arg6)
{
	return INLINE_SYSCALL(nr, arg1, arg2, arg3, arg4, arg5, arg6);
}

I don't have a copy of glibc to hand, so i'm not quite sure on the syntax
of INLINE_SYSCALL.

Ooops.  Clearly, that needs to get fixed.
