------- Comment #3 from lucier at math dot purdue dot edu 2007-03-10 17:44 ------- Removing the build directory from the source tree got rid of this problem for me.
So I don't know what people want to do about this bug. Over the years some people have worked to fix such problems as bugs; and some people want to point to the documentation and say "Tough, don't put the build directory in the source tree." -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31122
