[bug #30829] vpath conflict with file mention in makefile vs file on disk

                 Summary: vpath conflict with file mention in makefile vs
file on disk
                 Project: make

Details:

Using 3.81
Perhaps this is garbage in garbage out:

Files:

$ ls woo sue
sue:
boo.h

woo:
$

Makefile:

$ cat vp.mk
a.o: woo/boo.h
# a.o: sue/boo.h

# succeed
# vpath %h sue woo
# fail
vpath %h woo sue


%.enu: %.h
        echo enu_BUILD_success $@ $<

all: boo.enu
        echo ALL success $@
$

when you run:

./gnumake.exe -f vp.mk all

gnumake finds woo/boo.h in vpath.c with the function selective_vpath_search
(lookup_file line ~488).
It then does not check for the file on disk.

With

vpath %h sue woo

The lookup_file fails and the file is found with dir_file_exists_p.

The problem is the incorrect info:
a.o: woo/boo.h

I found the behaviour at first surprising.
