I haven't used combined tree builds of binutils+gcc for a very long time, so this issue wasn't on my radar at all, sorry. > Globally replacing > configure.in by configure.[ai][cn] appears to address this, but I'm not > sure whether that would be an acceptable change Certainly sounds reasonable. > (there doesn't seem > to be a fix for this in gcc trunk either, which I originally expected I could > simply backport). The configure.in->configure.ac rename happened over a year ago so I guess this shows that not too many people use combined binutils+gcc builds nowadays. I've always found combined binutils+gcc builds not worth the bother compared to simply building and installing binutils first, as Jim suggests. -- Alan Modra Australia Development Lab, IBM
