Ok, I understand. Actually, looking at the sysconf man page:
KERNEL_BITS _SC_KERNEL_BITS Returns the number of
bits used by the kernel
for pointer and long
data types. Current
values include 32 and
64.
It doesn't directly indicate that the OS is capable of dealing with
64-bit binaries. On PA2.0 machines that have wide PDC calls, the
parisc-linux kernel runs in 64-bit mode but binaries run in narrow mode
without the W bit set.
As far as package configuration goes, I doubt that we care about the
number of bits used by the kernel for pointers, etc. We care about the
code architecure for binaries and the data model. Thus, it might be
better if this was changed to my original preconception.
