Using 3.81
Perhaps this is garbage in garbage out:


$ ls woo sue



$ 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.


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.
