The root of the problem is that Windows environment variables are not case sensitive, while they *are* in a Unix environment.  Cygwin passes an environment block with duplicate identically-named variables (if case insensitive; unique if case sensitive), and this will make some Windows programs go boom, because they assume the block is maintained in a case-insensitive manner.

At the very least, it won't necessarily give you the answer you expect (if both "TEMP" and "temp" store different values and you do a case insensitive lookup of "TeMp", which is going to be returned if you don't crash?)

There is a test release for base-files addressing this issue. Could
you try if that solves this problem for you?
