Thank you. I like that OE is finally using this feature and that we could have a ro source

the macro is defined here[1] and on a very quick (<30s) look line-map doesn’t allow
any remapping. This means OE is the first buildsystem to systematically apply the
B != S? My hackish(?) solution would be to force __FILE__ to behave like __BASE_FILE__.
