Set PRIV(buf_size) and return it
This is a little tricky since it should be portable.
The openVMS object file has 'variable length' which means that
read() returns data in chunks of (hopefully) correct and expected
size. The linker (and other tools on VMS) depend on that. Unix
doesn't know about 'formatted' files, so reading and writing such
an object file in a Unix environment is not trivial.
With the tool 'file' (available on all VMS FTP sites), one
can view and change the attributes of a file. Changing from
'variable length' to 'fixed length, 512 bytes' reveals the
record size at the first 2 bytes of every record. The same
may happen during the transfer of object files from VMS to Unix,
at least with UCX, the DEC implementation of TCP/IP.
The VMS format repeats the size at bytes 2 & 3 of every record.
On the first call (file_format == FF_UNKNOWN) we check if
the first and the third byte pair (!) of the record match.
If they do it's an object file in an Unix environment or with
wrong attributes (FF_FOREIGN), else we should be in a VMS
environment where read() returns the record size (FF_NATIVE).
Reading is always done in 2 steps:
1. first just the record header is read and the size extracted,
2. then the read buffer is adjusted and the remaining bytes are
read in.
All file I/O is done on even file positions. */

Image files (executable or shared images) are stored as a raw

each records are preceeded by its length (on a word - 2 bytes), and

are transfered to a UNIX filesystem (using ftp), records are lost.
Only the raw content of the records are transfered. Fortunately,
