Agreed, ACK.

If we had a separate 'Path' type in the generator, then these checks
could be automated.

That is to say, splitting the existing String variant into String .. |
Device .. | Path .. | DeviceOrPath .., where DeviceOrPath is just
needed for the couple of functions that wrongly take a string which
could be a device or a path ('file' being one of these).

Also note that most (all?) paths get rewritten in the non-generated
code to prefix them with the content of the sysroot global variable.
(See: sysroot, sysroot_path and the %R custom printf spec).  This is
particularly error-prone and probably another candidate for
automation.

Rich.
