-W does not work with vpath

[Maciej Walezak]

Hello there,

My makefile looks like this:

vpath %.c src
file.o: file.c
        cp $< $@

The file "file.c" is in "src" directory. Now consider the following sequence of 
commands:

$ make
cp src/file.c file.o
$ make -W src/file.c 
make: `file.o' is up to date.

It looks like -W does not work for files found via vpath directive. Is it a bug 
or a feature?

greetings
