Subject: Fix compiling on GNU/Hurd. [skip appveyor]
X-Git-Url: https://git.tcpdump.org/tcpdump/commitdiff_plain/6cf3ea7d0f7c43440f74c93b95a7864f30fc68b4?hp=6cf3ea7d0f7c43440f74c93b95a7864f30fc68b4

Fix compiling on GNU/Hurd. [skip appveyor]

GNU/Hurd does not define MAXHOSTNAMELEN because it does not define
HOST_NAME_MAX, even if __USE_POSIX is defined.  This causes the
following:

./print-bgp.c:1997:14: error: 'MAXHOSTNAMELEN' undeclared (first use in
  this function)
./print-bgp.c:2965:14: error: 'MAXHOSTNAMELEN' undeclared (first use in
  this function)
./print-icmp.c:502:11: error: 'MAXHOSTNAMELEN' undeclared (first use in
  this function)

However, the above code should not depend on this OS-specific detail to
size its temporary printing buffers, so just hard-code the sizes.
