--- Comment #3 from Peter Bergner <bergner at gcc dot gnu.org> --- So this ends up not being a git conversion issue. I can also get this to fail using my svn tree as well now. The problem seems to be the choice in gcc source tree directory name. I had chosen "gcc.git" to make it easy to identify from the svn trees I still have a round. If I rename that to "gcc-git", then my build completes fine with no problem. If I rename my gcc svn tree to "gcc.svn", then it too fails. Strangely, using "gcc.foo" seems to be ok. Is there something special about source directory names "gcc.svn" and "gcc.git"?
