3:43 p.m.
I needed to add a few patches to be able to build libguestfs 1.20.2
out of tree. Mostly srcdir/builddir issues -- I think that I had
posted something for building the daemon before.
As mentioned on IRC, I found that compiling (Ruby bindings) caused
config.h file shipped with the Ruby headers to be included rather than
${builddir}/config.h. This can be fixed because the relevant checks
can be performed in the extconf.rb script as well.
Cheers,

Weird ... but ... ACK. I wonder why we don't see this error on
Fedora? In any case I can't see any problem with linking
libguestfs-test-tool to gnulib. In fact I don't know why we weren't
doing that already.

I think it's probably better to compile without --enable-gcc-warnings.
In the Fedora package we don't use that option. I only use it on my
local machine.
Unless this error still happens even without that option?

I can reproduce this error too on Wheezy. It seems to be a bug in
Ruby (1.9.1). It doesn't occur in 1.9.3 that we have in Fedora.
