Init.sh sets them as shell variables; they aren't exported to the
environment.

That makes sense. Tcl uses forward slash internally on all platforms. 
It suspect that it requires the use of "file normalize ..." on
Windows.

Yep; the startup code sets env(GISDBASE) etc via g.gisenv, which will
override any external settings (which shouldn't be there anyhow).
