I am still looking at it, but since this patch (but at least from a timing perspective), it looks like "make install" uses the build compiler, not the just built compiler, and hence fails when the former is older and does not grok flags supported in newer versions of GCC. (This may also predate this change, and for some reason now make install invokes builds when it did not do so earlier, or it is something different, but something's odd.) Gerald
