The procedure in select.tcl DOES have global env...

proc GSelect_::create { element args } {
    # main procedure for creating and managing selection window, which a
tree
    # within a scrolling window.

    global env id

...However, gui.tcl sets env(GISDBASE) etc outside of any procedure (i.e.,
runs these before any procedure). But there is no global env statement.
Maybe this is needed for Windows?
