Query on linking order

[john o goyo]

Greetings, Gaius.

What is the linking order for gm2?

Reason: When linking, it seems that gm2 looks in the current directory 
even though there is no reference to the current directoy.

Example: Note the following sequence.

[~/prj/tst]=> cat first.mod
MODULE first;

   FROM InOut IMPORT WriteString, WriteLn;

BEGIN
   WriteString("Modula-2. What else?"); WriteLn;
END first.

[~/prj/tst]=> cat IO.def
DEFINITION MODULE IO;

(*
 * Test module for gm2 linking order.
 *)

PROCEDURE Something(i :CARDINAL) :CARDINAL;

END IO.

[~/prj/tst]=> cat IO.mod
IMPLEMENTATION MODULE IO;

(*
 * Test module for gm2 linking order.
 *)

PROCEDURE Something(i :CARDINAL) :CARDINAL;
BEGIN
  IF ODD(i) THEN RETURN i + 1
END Something;

END IO.

[~/prj/tst]=> gm2 -c first.mod
[~/prj/tst]=> gm2 first.mod
./IO.mod:10:5: warning: In procedure : syntax warning,  missing
   10 | END Something;
      |     ^~~~~~~~~
/home/build/gcc/13.1.0/lib/gcc/sparc-sun-solaris2.11/13.1.0/m2/m2pim/StdIO.mod:163:18:

It seems that gm2 tries to include the IO.mod is the current directory, 
despite no directive to do so.

I could not find anything relevant in the gm2 documenation.

Please advise.

Sincerely,
