Linking with -lvdeplug without checking whether it exists causes
failures from later configure tests; this makes it an optional
dependency in the same way as other libraries.
Note that it appears that a 'make clean' may be required due to the
change in user_strings_unix.h failing to cause all of the modules that
include it to be rebuilt.
Now that issue #154 has been fixed, when Basilisk II is configured to
use "tun" for networking, the generated tunN interface can be bridged,
enabling AppleTalk frames to be forwarded without the Linux host
needing to be able to route AppleTalk.
This commit updates the README to discuss this possibility and briefly
outline how it can be achieved. A number of spelling corrections and
other minor clarifications are made in the same area.
Previously, when "ether tun" configuration was used on a Linux host,
packets were sent with Ethernet/MAC address 00:00:00:00:00:00. Under
CentOS 7 at least, this did not appear to cause any issues where the
tun interface on the host was configured with an IP address, but when
an attempt was made to bridge the tun interface, it was no longer
possible to establish IP communication between the emulated machine
and either the Linux host or a Windows NT Server 4 VM.
This fix causes an Ethernet/MAC address to be generated in the same
way when using TUN/TAP as is done for ethertap.
c18d6fa removed a space from BasiliskII/src/Unix/configure.ac, which
caused "configure" to fail to properly determine the correct set of
libraries to link against when using X11, which caused linking to
fail. This fix restores the missing space.
Previously, "checking whether TUN/TAP is supported..." in "configure"
failed to detect TUN/TAP support due to compile errors due to "struct
sockaddr" not being defined. This fix causes sys/socket.h to be
#included if it exists.
