Attachment: snippet of build log, w/ a bunch of instances of this warning

I'm getting many copies of this build warning, when doing a debug build of up-to-date mozilla-inbound w/ gcc 4.7.2 on Ubuntu 12.10:
{
0:54.94 In file included from /scratch/work/builds/mozilla-inbound/mozilla/js/src/jsscope.h:14:0,

}

I'm attaching a snippet of my clobber build output that includes all of these build warnings for various .cpp files that include jsobj.h and spam about this.

I believe this function declaration "asModule()" was added in bug 568953 -- I originally posted about this over there, but I'm spinning this off as a separate bug so as not to clutter up that bug too much.

Bug 568953 was merged over to m-c, so this affects m-c builds now, too.
