I'm trying this now, in conjunction with the patch posted at http://gcc.gnu.org/bugzilla/show_bug.cgi?id=53348#c7 So far, your change seems to address the O2ggnu++0x.gch error in the original report above, as I encountered that before actually making the change. (Bootstrap time on this system is measured in days, and I'll probably need to do a second go-around, so let me get back to you...)
