fix for: assignment discards qualifiers from pointer target type

["Carl B. Constantine" <duckwing duckwing ca>]

I'm getting the following warning message on compile:

filename.c:124: warning: assignment discards qualifiers from pointer
target type.

This occurs on lines such as this:

...
gchar   *userid = NULL;

userid = gtk_entry_get_text(GTK_ENTRY(lookup_widget(logon, "password)));

but, gtk_entry_get_text returns a gchar* (specifically a G_CONST_RETURN
gchar*). 

So my question is, how on earth do I fix this warning message? Am I
casting something incorrectly?
