--- Comment #5 from Ian Lance Taylor <ian at airs dot com> 2012-02-21 18:33:14 UTC --- If ARM GNU/Linux does not support getcontext/setcontext, then this particular configure test is not particularly relevant, since the library isn't going to work anyhow. I suppose the error message could be more clear but it's going to boil down to a compilation or runtime error regardless.
