is that fseeko() fails in very predictable and frequent ways on ia64.
This is because the offset is actually an address in the process'
address space, which on ia64 can be larger than long (for lseek) or
off_t (for fseeko). The crux is the signedness. The register stack
and memory stack are in region 4 on ia64. This means that the sign bit
is 1. The large positive virtual address is wrongly interpreted as
a negative file offset.
There's no quick fix. Even if you get around the API by using a
SEEK_SET up to LONG_MAX and follow it up with a SEEK_CUR for the
remainder, the kernel simply cannot deal with it. and the second
seek will just fail.
Therefore, this change does not actually fix the root cause. It just
makes sure we're not spitting out all kinds of garbage or that the
get_struct() function in particular does not cause truss(1) to exit.
This, I might add, invariably happened way too soon for truss(1) to
be of any use on ia64...
o Syscall return values do not fit in int on 64-bit architectures.
Change the type of retval in <arch>_syscall_exit() to long and
change the prototype of said function to return a long as well.
o Change the prototype of print_syscall_ret() to take a long for
the return address and change the format string accordingly.
o Replace the code sequence
tmp = malloc(X);
sprintf(tmp, format, ...);
with X by definition too small on 64-bit platforms by
asprintf(&tmp, format, ...);
With these changes the output makes sense again, although it does
mess up the tabulation on ia64. Go widescreen...

sometimes, su will receive a SIGTTOU when parent su tries to set child
su's process group as foreground group, and su will be stopped unexpectly,
ignoring SIGTTOU fixes the problem.

subtract one unsigned number from another potentially smaller

if_xname, if_dname, and if_dunit. if_xname is the name of the interface
and if_dname/unit are the driver name and instance.
This change paves the way for interface renaming and enhanced pseudo
device creation and configuration symantics.

different sets of definitions in /usr/include/rpcsvc, mostly compatable,
but with different names. Will the real one please stand up?
In order to get prototypes for yp_maplist, we had to use the 'other'
naming system.
(portability warnings) switch is used. Add -Wno-system-headers after it so
that we dont get 500 screenfulls of warnings about #elif in /usr/include.
I'm not entirely happy with this. Maybe cdefs.h shouldn't use #elif and
instead nest #else clauses?
