    POSIX DEPENDENT TYPES

    These definitions give the POSIX types required in this module.
    Dummy definitions for non-POSIX systems are also given.  The default
    value for FS_POSIX is given in ossg_api.h.  The loss in functionality
    with the non-POSIX definitions is minimal (#import may not work in
    obscure cases, the file datestamps in diagnostics mode may be wrong).
