Well, "__base_ctor" is nothing to do with us, so this sounds like a
toolchain issue.  Google turns up a few hits for "__base_ctor is
deprecated", but I didn't see anything explaining it.

If you can find a fix, I can try to slot it into configure or the

You can work around it by just building the problematic file without

make CXXFLAGS=-Wno-error api/omquery.lo

And then "make" again to continue the build as normal.  If this is
widespread, just disable -Werror globally:

make CXXFLAGS=-Wno-error

Note that -Werror is only ever automatically enabled by
--enable-maintainer-mode, so this doesn't affect users building from a
tarball in the usual way.
