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