Yes.

Something like

{$ifdef cpu386}
{$ifdef linux}
{$define linux386}
{$endif}
{$endif}

Yes, that's what baseunix and unix are ( and sockets,termio,syscalls etc).

It is not complete by far, but it is getting there. If I can get the "users"
package cleaned up, some more reasons to use unit libc disappear.

This also because mixing units can lead to problems since they are separate
collections of types.
