This patch for GNU Mach broke binary compatibility with OSKit-Mach.

  OSKit-Mach            GNU Mach
0 skip                  i386_io_port_add
1 skip                  i386_io_port_remove
2 skip                  i386_io_port_list
3 i386_set_ldt          i386_set_ldt
4 i386_get_ldt          i386_get_ldt
5 i386_io_perm_create   i386_set_gdt
6 i386_io_perm_modify   i386_get_gdt
7 i386_set_gdt
8 i386_get_gdt

I'm about to add `i386_io_perm_create' and `i386_io_perm_modify' to GNU
Mach.

As there is already at least one person (Samuel) to use the
`i386_set_gdt' and `i386_get_gdt' routines on GNU Mach (in glibc) and I
don't know of anybody who is actively using OSKit-Mach (Roland, do you
still have it running somewhere?) I suggest that we change OSKit-Mach to
match what GNU Mach has.

 Thomas
