Ok, I understand better now.  Altough it's a bit off-topic here, I would
like to know where I can understand these subtleties.  Instinctively, I
would say that /usr/include/{asm,linux}/ need to point to the current
kernel headers in order to use an API in sync with the running kernel :
for example, imagine a kernel patch which adds the incoming and outgoing
interfaces in the tuple used by connection tracking in the NetFilter
framework ; /usr/src/linux/include/linux/netfilter_ipv4/ip_conntrack_tuple.h
would be modified, and so applications including
<linux/netfilter_ipv4/ip_conntrack_tuple.h> for any reason would not
use the correct structure.
I must be missing something, but I can't get what.  Please tell me.

Thanks in advance,
