No.  Cygwin goes out of its way to change environment variables to upper
case.  Environment variables in windows, on NT+ at least, can be mixed
case.  Unfortunately, sometimes you find things like "Path" instead of
"PATH" so Cygwin needs to rectify that.

To repeat, translating environment variables to uppercase is something
that *cygwin* does.  Check out environ.cc for more information.
