   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
769
   All file I/O is done on even file positions.  */
