Question: Is CAREFUL_ALIGNMENT=1 needed for rsync on RISC-V
...to assume that only x86 CPUs can handle memory misalignments:
```c
/* We know that the x86 can handle misalignment and has the same
?* byte order (LSB-first) as the 32-bit numbers we transmit. */
#if defined __i386__ || defined __i486__ || defined __i586__ || defined
__i686__ || __amd64
#define CAREFUL_ALIGNMENT 0
#endif
#ifndef CAREFUL_ALIGNMENT
#define CAREFUL_ALIGNMENT 1
#endif
```
Thus, when copying 4-bit integers (just an example), rsync uses direct
copies on x86:
```c
static inline uint32
IVALu(const uchar *buf, int pos)
{
?? ?union {
?? ???? const uchar *b;
?? ???? const uint32 *num;
?? ?}...

rsync3 universal binary for Mac OS X?
Did anyone ever get rsync3 to compile as a universal binary and work
correctly on both tiger and leopard on ppc and intel?

Rsync dies with "Invalid file index:" error message
Hi all,
i'm having a rather strange problem with rsync (v2.6.8). Rsync is run to synchronize
two identical, rather old Solaris 2.6 servers. All filesystems rsync fine except for one.
Rsync bails out on this particular FS with the following messages:
# /var/tmp/bin/rsync -avz -e "ssh -i $keyfile" --exclude-from=/tmp/rsync_data.excl server:/data/ /data
receiving file list ... done

I'm getting the same number (1610612736), and I also note that 524288
is a suspicious-looking number as well (0x80000). I don't think there
is a byte-ordering issue at play here. The configure script...
