warning messages in qt2 and qt3

You may get some warnings running qt2 or qt3 applications.
such as "Locales not supported" (in both qt2 and qt3), or
"qstring_to_xtp result code -2" (in qt2).
You can either ignore those warnings, or set your locale
properly. I have the following in my $HOME/.profile

export LC_ALL="en_US"
