Needs to depend on lseek, particularly since pread is replaced on mingw, and 
mingw has an lseek bug with non-seekable files (like pipes).

Perhaps test-pread.sh should also check that pread fails with ESPIPE on a non-
seekable fd?  Also, the test should probably cover EINVAL for trying to read 
negative offsets.
