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. I'm reporting it here rather than upstream, as drive letter handling may be cygwin-specific; but you may decide that the regression is upstream. Meanwhile, I'll also report to the bash list that use of .: is no longer portable in VPATH designations. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
