738 This is a little tricky since it should be portable.
739
740 The openVMS object file has 'variable length' which means that
741 read() returns data in chunks of (hopefully) correct and expected
742 size. The linker (and other tools on VMS) depend on that. Unix
743 doesn't know about 'formatted' files, so reading and writing such
744 an object file in a Unix environment is not trivial.
745
746 With the tool 'file' (available on all VMS FTP sites), one
747 can view and change the attributes of a file. Changing from
748 'variable length' to 'fixed length, 512 bytes' reveals the
749 record size at the first 2 bytes of every record. The same
750 may happen during the transfer of object files from VMS to Unix,
751 at least with UCX, the DEC implementation of TCP/IP.
752
753 The VMS format repeats the size at bytes 2 & 3 of every record.
754
755 On the first call (file_format == FF_UNKNOWN) we check if
756 the first and the third byte pair (!) of the record match.
757 If they do it's an object file in an Unix environment or with
758 wrong attributes (FF_FOREIGN), else we should be in a VMS
759 environment where read() returns the record size (FF_NATIVE).
760
761 Reading is always done in 2 steps:
762 1. first just the record header is read and the size extracted,
763 2. then the read buffer is adjusted and the remaining bytes are
764 read in.
