Bug#486530: libxcb: does not work on GNU/kFreeBSD

[Petr Salinger]

Package: libxcb
Severity: important
Version: 1.1-1.1
Tags: patch
User: [EMAIL PROTECTED]
Usertags: kfreebsd


Hi,

the current version does not work on GNU/kFreeBSD.

The GNU/kFreeBSD (and BSDs in general) have a different
layout of struct sockaddr, sockaddr_in, sockaddr_un ...

The first member do not have to be "sa_family",
they also have "sa_len" field.

Please apply attached patch and run

  ./autogen.sh

It would also be nice if you can ask upstream
to include this change.

Thanks in advance

                        Petr
