OK, I see. The current FExpand implementation might allow even including
it twice with two different contexts / conditional defines (although not
within the same namespece/unit) if that is useful for your needs. The
other option is obviously always converting the paths to the native format
(and possibly back) in case of invocation from the "foreign" context as
suggested by you. Native Amiga paths should be hopefully supported well by
the existing FExpand implementation. However, if you find any issues,
please provide the appropriate test cases (preferably as a diff to
tfexpand.pp, but pairs input_path / expected_output together with
description of the starting situation regarding the current directory,
etc., are OK too) and I'll be happy to fix it.
