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