Corinna Vinschen 030d86d04d TZ: Replace unreliable isupper calls on wchars
In case the TZ variable is empty, Cygwin fetches timezone info from
Windows.  Extracting the timezone short name uses isupper on wide chars.
Replace with explicit check for A <= character <= Z to be independent
of undefined behaviour.
