Many times, we don't notice a bug in src/libvirt_private.syms
until someone attempts a build with modules enabled. Likewise,
some gcc warnings about no % in a printf format string only
appear under --disable-nls. And configure.ac should automatically
be excluding modules on mingw without us having to be explicit.
Improving autobuild.sh to stress more combinations can only help.

Thanks for the review; however, I will defer pushing this patch until I
also have time to fix a couple of fallout problems (my goal is to get
this all squared away before 0.9.9). In particular, ./autobuild.sh now
fails with:
CCLD libvirt_driver_nwfilter.la
../gnulib/lib/.libs/libgnu.a(allocator.o):(.data.rel.ro+0x0): multiple
definition of `stdlib_allocator'
../gnulib/lib/.libs/libgnu.a(allocator.o):(.data.rel.ro+0x0): first
defined here
that is, I think we're incorrectly linking gnulib in from multiple
helper libraries somewhere along the way.

Thanks for the review; however, I will defer pushing this patch until I
also have time to fix a couple of fallout problems (my goal is to get
this all squared away before 0.9.9). In particular, ./autobuild.sh now
fails with:
Hmm, I presume this is due to the addition of '-with-driver-modules'.
If so, please push the other bits of your patch, and leave the driver
modules bit for later.

Done, and I'll see what I can do about --with-driver-modules later.

I'm pushing this under the build-breaker rule, which gets me to the next
build failure that I'll be patching soon:
Creating library file: .libs/libvirt.dll.a

Subject: [PATCH] build: disable dtrace on non-Linux builds
Using dtrace (and systemtap in general) is Linux-specific.
Running ./autobuild.sh shows that attempting a cross-build to
target mingw was mistakenly trying to build dtrace code, merely
because it was present on the compilation host.
* configure.ac (with_dtrace): Don't attempt to use dtrace when
doing a cross-build hosted on Linux but targetting elsewhere.
Reported by Daniel P. Berrange.

Actually, that error only occurs when using Dan's 8-patch series to
avoid the hangs when an event fires after the connection is down (but we
need to get that series polished and in soon, as I can't complete
autobuild.sh without it).

host has it present for native. So we either need to fix configure.ac
or add --without-dtrace back in.
It looks like --without-python is also essential, as I'm now getting:

Why is a mingw build trying to include /usr/include/python2.7/Python.h
instead of the appropriate mingw-specific buildroot? It seems like our
python detection in configure.ac is misbehaving during cross-builds.

I took at look at the python code detection & ran away screaming. Until
someone decides to rewrite it to not suck, I've re-added --without-python
to autobuild.sh so we can get working automated builds again.
