Hi,
the current cvs head does not compile on s390-64. I had to
add files for pread, pread64, pwrite and pwrite64 in the
s390-64 sysdeps folder to get the alias/hidden definitions
right. I don't know if there is a better solution, this at least
works.
blue skies,
Martin.

* sysdeps/unix/sysv/linux/s390/s390-64/pread.c: New file.
* sysdeps/unix/sysv/linux/s390/s390-64/pwrite.c: New file.
* sysdeps/unix/sysv/linux/s390/s390-64/pread64.c: Replace empty file
with real implementation.
* sysdeps/unix/sysv/linux/s390/s390-64/pwrite64.c: Likewise.
* sysdeps/unix/sysv/linux/s390/s390-64/syscalls.list: Remove pread
and pwrite entries.
