[Libvir] [PATCH] A variety of fixes for Debian, old versions of GnuTLS

Attached is a patch to get libvirt working on Debian/stable again. (1) Add ./configure option --disable-stack-protector. The stack protector feature is still enabled by default, but it causes no end of problems when compiling on Debian systems, apparently because of bugs in their gcc. So Debian users would be well advised to try disabling it if they have problems building. (2) Adds support for GnuTLS 1.0.x by detecting this version and enabling some simple compatibility macros. (3) In qemudDispatchClientEvent, a prototype shadowed a global function name. A simple name change to a parameter fixes it. (4) Debian (and likely non-Linux systems also) don't have the SIOCBRADDBR and related ioctls. If these are missing, then I've changed this to runtime errors. This means that these systems won't be able to start the network daemon, but other (non-network) features of libvirt continue to work. (5) Removed a warning in src/qemu_conf.c. Rich. PS. You need to drop the file gnutls_1_0_compat.h into src/ subdirectory. Sorry this file isn't in the proper patch but I don't have write access to CVS from the testing machine. -- Emerging Technologies, Red Hat - http://et.redhat.com/~rjones/ Registered Address: Red Hat UK Ltd, Amberley Place, 107-111 Peascod Street, Windsor, Berkshire, SL4 1TE, United Kingdom.
