[Qemu-devel] [PATCH 00/11] configure: Fix -Werror issues

[Peter Maydell]

This patch series:
 1. turns off -Werror for configure tests
 2. fixes a large pile of warnings in various configure tests
 3. turns on -Werror for configure tests again, but in a way that means
    that errors mean configure stops so the warnings are as obvious
    to developers as they would be for a -Werror compile of the main code

The "turn off -Werror" patch has already been sent to the list;
I've included it here as it is a dependency, but it should probably
be committed ASAP even if the rest of this series needs review and
updating. I've also put all of Stefan's recent patches in since without
them configure won't run once -Werror is reenabled.

NB: this works for me, but it's possible there are some still lurking
warnings in a few compilation tests that are themselves protected by
tests for some library/host I don't have. They should be easy to fix
as they turn up, though, and the configure failure message is clear
about how to work around in the meantime.
