+a mental note... building git-annex in a windows vm ATM, and saw

+
+so either the check is wrong or there are multiple `cp` around (may be some came with `stack`?) ... I found total over 10 different cp.exe on drive (didn't check yet how many in PATH). But I just wonder, if check is done at build time, but `cp` is not distributed along, the check should be done at run time instead.
