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.
