739 Set PRIV(buf_size) and return it
740
741 This is a little tricky since it should be portable.
742
743 The openVMS object file has 'variable length' which means that
744 read() returns data in chunks of (hopefully) correct and expected
745 size. The linker (and other tools on VMS) depend on that. Unix
746 doesn't know about 'formatted' files, so reading and writing such
747 an object file in a Unix environment is not trivial.
748
749 With the tool 'file' (available on all VMS FTP sites), one
750 can view and change the attributes of a file. Changing from
751 'variable length' to 'fixed length, 512 bytes' reveals the
752 record size at the first 2 bytes of every record. The same
753 may happen during the transfer of object files from VMS to Unix,
754 at least with UCX, the DEC implementation of TCP/IP.
755
756 The VMS format repeats the size at bytes 2 & 3 of every record.
757
758 On the first call (file_format == FF_UNKNOWN) we check if
759 the first and the third byte pair (!) of the record match.
760 If they do it's an object file in an Unix environment or with
761 wrong attributes (FF_FOREIGN), else we should be in a VMS
762 environment where read() returns the record size (FF_NATIVE).
763
764 Reading is always done in 2 steps:
765 1. first just the record header is read and the size extracted,
766 2. then the read buffer is adjusted and the remaining bytes are
767 read in.
768
