* sysdeps/mach/hurd/pread.c: Fail with EINVAL if OFFSET is negative.
* sysdeps/mach/hurd/pwrite.c: Likewise. * shlib-versions [USE_IN_LIBIO] (.*-.*-gnu-gnu.*): libc=0.3 [USE_IN_LIBIO && !GLIBC_OLDEST_ABI] (.*-.*-gnu-gnu.*): Use GLIBC_2.2.4 as default version set. (test_ftello): Check for EFBIG and ENOSPC, clean up error messages.
