These are the environment variables visible in my Cygwin environment.

echo "$PROGRAMFILES(x86)" is the equivalent of echo
"${PROGRAMFILES}(x86)" i.e. the value of $PROGRAMFILES, followed by
the fixed string "(x86)"

I tried

$ echo "${PROGRAMFILES(x86)}"
$ echo "${PROGRAMFILES\(x86\)}"

and bash outright refused them ("bad substitution"). So it may not be
possible to have an environment variable with ()s in its name.
