make cygwin package is using unpatched source code.
-- original message ----
This version of make introduces a regression in VPATH handling.
Bash uses VPATH = .:/path/to/sources
to specify a two-directory VPATH. Technically, the .: is redundant
(because make will automatically search the current directory before
resorting to VPATH rules), but that hasn't stopped bash from using it
anyways. (Most automake-based packages only use a one-directory VPATH
designation; but bash doesn't use automake)
The old version of make properly handled this as two directories; but
the new version of make is apparently treating it as a drive letter
directive and failing to look in /path/to/sources.
If I change bash to emit:
VPATH = . /path/to/sources
then things work again. Likewise if I change it to omit the redundant
leading '.:'. So I can work around the regression in the meantime.
