2012-11-22 Sebastian Huber <sebastian.huber@embedded-brains.de>
* libc/include/sys/reent.h (__sFILE): Change type of _offset
from int to _off_t.
Currently we have

This change breaks binary compatibility if sizeof(int) != sizeof(long).
It breaks binary compatibility also on some RTEMS targets, but this is
not a problem.
