Question make - foreach function
I wrote the following Makefile:

Code:
 
dirs := a b c d
files := $(foreach dir,$(dirs),$(wildcard $(dir)/*))
.PHONY: all
all:
    touch $(files)

The first two lines are taken from GNU make tutorial, Section 8.5 The foreach Function. I would expect the recipe
Code:
    touch $(files)

to be expanded to
Code:
    touch a:/* b:/* c:/* d:/*

In fact, GNU Make 3.82 for Windows expands it to
Code:
    touch

Can anyone explain this behavior?
