+ 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.
