Are you sure that this line in configure.ac isn't the root of the
problem?
OVS_ENABLE_OPTION([-Wdeclaration-after-statement])
I'm still really nervous about this one (I think it often uglifies code)
but let's give it a shot:

We have enough of these in the source that I think they're not a problem
in practice anymore, so let's delete this one too:
