Log Message:
Add one more patch, correcting sign extension in two places:

> From Wofgang Solfrank (ws@tools.de)
> What I discovered was a problem in ckddasd.c, where there are two lseeks
> with an offset of -(CKDDASD_RECHDR_SIZE).  Now CKDDASD_RECHDR_SIZE is
> defined (in hercules.h) as sizeof(CKDDASD_RECHDR), which happens to be
> an unsigned int.  Since the offset in the lseek (and in the ckd_lseek
> that is used as an interface routine to it) is of type off_t, i.e. 64-bit,
> the unsigned is zero-extended to 64 bits, and thus the sign is lost.
