Description quetschke 2007-06-02 03:06:14 UTC 
The dmake man page describes the :i macro expansion ( $(MACRO:i) ) as:
  i or I - inferred names of targets.

This needs some additional explanation: If the macro value corresponds to a target
(or prerequisite) the actuall corresponding filename might have been changed
because of the .SOURCE[.suffix] special target.

The following example prints /tmp/aaa if that file exists:

- - makefile.mk - -
SHELL*:=/bin/sh
SHELLFLAGS*:=-ce

.SOURCE : /tmp
QQQ:=aaa

all : aaa
	@echo $(QQQ:i)
