Good point, _main deserves indeed extra treatment. The startup code
is by the way in


with the call to _main in line 124.

This is indeed the intention. The rules to locate include files,
to link globals, or to decide what is kernel, lib, or user, is in
a configuration file. To set this up for 2.9 BSD or UNIX V7 and V6
should not be difficult, in particular if one starts with the more
complex case and goes back in history.
