So is it OK to move syscall.h into libgloss and remove access.c?

And further, is it a good idea to reuse the common syscall.h in 
libgloss? I did some work in the last week to do so. And I found we need 
three new syscalls to be added into the common syscall.h to support argc 
and argv: SYS_argc, SYS_argnlen and SYS_argn. Is it OK to add them to 
the common libgloss syscall.h?

Thanks,
