[PtP] Fix BSD problems with PtP interfaces: must treat RTA_BRD as peer address
2007-05-17 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
* kernel_socket.c: (ifam_read_mesg) Grab RTA_DST and RTA_GATEWAY
addresses from the message (if present, which seems unlikely on
current BSD platforms), and show them in the debug messages.
Also, add ifam_flags to the debug messages.
(ifam_read) If the interface is point-to-point, then the RTA_BRD
address should be treated as a peer address.

[autoconf] GNU_SOURCE can be defined twice, through AC_FUNC_STRNLEN
2007-05-10 Paul Jakma <paul.jakma@sun.com>
* configure.ac: Use AC_GNU_SOURCE to define _GNU_SOURCE, rather
than having lib/zebra.h do it.
AC_FUNC_STRNLEN has side-effects with latest autoconf, use
AC_CHECK_FUNC on strnlen instead.
* lib/zebra.h: Don't try define _GNU_SOURCE, autoconf should do it.

[autoconf] bugs 162,303,178: Fix 'present but can not be compiled' warnings
2007-05-09 Paul Jakma <paul.jakma@sun.com>
* configure.ac: sys/conf.h depends on sys/param.h, at least on
FBSD 6.2.
(bug #363) Should check for in_pktinfo for IRDP
2006-05-27 Paul Jakma <paul.jakma@sun.com>
* configure.ac: General cleanup of header and type checks, introducing
an internal define, QUAGGA_INCLUDES, to build up a list of
stuff to include so as to avoid 'present but cant be compiled'
warnings.
Misc additional checks of things missing according to autoscan.
Add LIBM, for bgpd's use of libm, so as to avoid burdening
LIBS, and all the binaries, with libm linkage.
Remove the bad practice of using m4 changequote(), just
quote the []'s in the case statements properly.
This should fix bugs 162, 303 and 178.
* */*.{c,h}: Update all HAVE_* to the standard autoconf namespaced
HAVE_* defines. I.e. HAVE_SA_LEN -> HAVE_STRUCT_SOCKADDR_SA_LEN,
* bgpd/Makefile.am: Add LIBM to bgpd's LDADD, for pow().
* ospf_spf.c: (ospf_vertex_new) Dont init vertices to infinity,
just let 0 be a special case.
(ospf_spf_add_parent) 0 distance candidate vertex is special,
cost still to be initialised - asserting that new distance
is <= existing only makes sense where w already has a cost.
(ospf_spf_next) Infinite cost links should not be followed,
bar those of the root.
