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.
