--- Comment #6 from Brett Neumeier <bneumeier at gmail dot com> --- Created attachment 36441 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=36441&action=edit document symptoms of problem and workaround Since the issue is a corner-case (it's only triggered when cross-compiling for certain architectures, using recent versions of GMP, and with in-tree GMP and ISL sources), and since there's an easy and obvious workaround, it seems pointless to spend a lot of time trying to adjust the build machinery. On the other hand, a something search reveals I'm not the only person to run into this situation, so it seems worthwhile to at least document the workaround. Here's a suggested paragraph -- it would have saved *me* a headache and a few hours of frustration when I tripped across the problem, so perhaps it will be helpful to someone else in the future?
