Please note that especially in this case, Cygwin != Windows. Cygwin
allows $path, $Path, $PATH, etc., to all coexist and be accessed case
sensitively. Exporting $path causes no problem, either. Should the eval
invoke a Windows program, $PATH is converted to Windows format and
exported, the other case-sensitive variants of path remain in the
environment and can be accessed by any program implementing
case-sensitive lookup as well. Not sure what will happen with
case-insensitive lookups, but a quick test showed that cmd.exe is not
bothered by $path given $PATH exists.
