[9fans] mk surprises me

[Bengt Kleberg <eleberg@cbe.ericsson.se>]

mk does not do what i expect it to do. here are some facts:


the mkfile

% : hdr.h

% : %.c
	cp $stem.c $target


the files
-rw-rw-r--   1 eleberg  avall          0 Mar 20 15:47 f2.c
-rw-rw-r--   1 eleberg  avall          0 Mar 27 13:12 f2
-rw-rw-r--   1 eleberg  avall          0 Mar 27 13:17 hdr.h


the test
; inferno/Solaris/sparc/bin/mk -f mkfile f2
mk: no recipe to make 'f2.c'


according to my interpretation of 'maintaining files on plan9 with mk'
(from plan9v2 documentation), page 188, the mkfile should produce f2
from f2.c if hdr.h is younger then f2. but instead i get the error
message above that i do not understand.
is there anybody that sees where i go wrong?

possible sources of errors:
i use mk from inferno, not plan9
i have only the plan9v2 documentation, not v3 documentation.
i am not very good with mkfiles
