696 Set PRIV(buf_size) and return it
697
698 This is a little tricky since it should be portable.
699
700 The openVMS object file has 'variable length' which means that
701 read() returns data in chunks of (hopefully) correct and expected
702 size. The linker (and other tools on VMS) depend on that. Unix
703 doesn't know about 'formatted' files, so reading and writing such
704 an object file in a Unix environment is not trivial.
705
706 With the tool 'file' (available on all VMS FTP sites), one
707 can view and change the attributes of a file. Changing from
708 'variable length' to 'fixed length, 512 bytes' reveals the
709 record size at the first 2 bytes of every record. The same
710 may happen during the transfer of object files from VMS to Unix,
711 at least with UCX, the DEC implementation of TCP/IP.
712
713 The VMS format repeats the size at bytes 2 & 3 of every record.
714
715 On the first call (file_format == FF_UNKNOWN) we check if
716 the first and the third byte pair (!) of the record match.
717 If they do it's an object file in an Unix environment or with
718 wrong attributes (FF_FOREIGN), else we should be in a VMS
719 environment where read() returns the record size (FF_NATIVE).
720
721 Reading is always done in 2 steps:
722 1. first just the record header is read and the size extracted,
723 2. then the read buffer is adjusted and the remaining bytes are
724 read in.
725
