+/* Get next record from object file to vms_buf
+   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 length at the first 2 bytes of every record. The same
+   happens during the transfer of object files from vms to unix,
+   at least with ucx, dec's implementation of tcp/ip.
+  
+   The vms format repeats the length 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.
+   first just the record header is read and the length extracted
+   by get_header_values
+   then the read buffer is adjusted and the remaining bytes are
+   read in.
