I am trying out apout using the "1972_stuff"

"as" to assemble "ux" (e10-01 through e10-02) it gives an error
"m 0024" (multiply-defined label) for the line:
mount: .=.+1024.
I assume this is because the assembler has predefined the "mount"
system call (I ran across this earlier when using my system call
table sys.s with ux with the v7 assembler).
It does look like this is the case. The manual says that syscall names
are pre-defined, and in these source fragments from 1972, you can see
that as definitely knows about mount and open:

I've sent an e-mail to Dennis to see if he can remember what the procedure
was to rebuild the kernel from the assembly source.
