-**
-**  Replacement for a missing pread.
-**
-**  Written by Russ Allbery <rra@stanford.edu>
-**  This work is hereby placed in the public domain by its author.
-**
-**  Provides the same functionality as the standard library routine pread
-**  for those platforms that don't have it.  Note that pread requires that
-**  the file pointer not move and without the library function, we can't
-**  copy that behavior; instead, we approximate it by moving the file
-**  pointer and then moving it back.  This may break threaded programs.
