697 Set PRIV(buf_size) and return it
698
699 This is a little tricky since it should be portable.
700
701 The openVMS object file has 'variable length' which means that
702 read() returns data in chunks of (hopefully) correct and expected
703 size. The linker (and other tools on VMS) depend on that. Unix
704 doesn't know about 'formatted' files, so reading and writing such
705 an object file in a Unix environment is not trivial.
706
707 With the tool 'file' (available on all VMS FTP sites), one
708 can view and change the attributes of a file. Changing from
709 'variable length' to 'fixed length, 512 bytes' reveals the
710 record size at the first 2 bytes of every record. The same
711 may happen during the transfer of object files from VMS to Unix,
712 at least with UCX, the DEC implementation of TCP/IP.
713
714 The VMS format repeats the size at bytes 2 & 3 of every record.
715
716 On the first call (file_format == FF_UNKNOWN) we check if
717 the first and the third byte pair (!) of the record match.
718 If they do it's an object file in an Unix environment or with
719 wrong attributes (FF_FOREIGN), else we should be in a VMS
720 environment where read() returns the record size (FF_NATIVE).
721
722 Reading is always done in 2 steps:
723 1. first just the record header is read and the size extracted,
724 2. then the read buffer is adjusted and the remaining bytes are
725 read in.
726
