Silly Windows.

I don't know if Solaris x86's tun driver works the same way as the
Solaris sparc32 tun driver. Apparently not...

Ah... most libc's allow you to pass a NULL pointer when printing
strings, they will print it as "(null)". Apparently the libc on Solaris
x86 doesn't check for that. In send_request(), c->name should be
replaced by c->name ?: "unknown" or something like that.

You can also run tinc with the -d5 -D options on the Windows machine, or
use the --logfile option to write it to a file.

And next time, please send files as attachments!
