Hi,
This is my first posting to the GNU Make mailing lists, so please let me know
if i've contravened any expectations.
## Background
I am a somewhat heavy user of GNU Make, and frequently want to do something
like the following:
FILE_SHA = $(shell sha256sum src/file.c)
deploy-frobnic
script:
http_//foo.bar :
$(GET) $(subst _,:,$@)
or whatever (obviously _ is not a good choice but you get the idea).

pathname might be different (the prefix and the .obj or whatever

without needing VPATH.
BTW, that vpath field seems to be left in there by accident, it appeared
in GNU make 3.77 but it's never been

That's not the problem. The problem is you're misusing VPATH.
VPATH is designed to find _sources_. It cannot be used to find
_targets_. It won't work to use it like that.
