appropriately, and that GNUmakefile and the MSVC++ project file define
it apppriately, as we do with libpcap, rather than defining it in
"interface.h".
Undo the rcsid-shuffling and addition of extra #includes, as we no
longer need to arrange that "interface.h" be included before using _U_
in an RCS ID or copyright.
use "_U_" in the definitions of "rcsid[]", to eliminate
complaints about those variables being unused;
move the definitions after the include of "interface.h", or add
an include of "interface.h", so that "_U_" is defined.
Include "config.h" before including "tcpdump-stdinc.h" in
"missing/datalinks.c".
safer way to terminate "pcap_loop()" in a signal handler (it just sets a
flag, it doesn't muck with data structures that might have been in the
middle of being updated).
Have "setsignal()" not request SA_RESTART, so that if we call
"pcap_breakloop()" in a signal handler and then return, we don't restart
a call that was waiting for captured packets, we just make that call
EINTR out.
