Sorry, I have it in my perf/urgent branch and the latest signed tag (perf-urgent-for-mingo), but I only pushed the later, just pushed the former now. Ingo should process those two soon, as they are purely bug fixes. I'll go through this new patchkit now, thanks for considering my suggestions. - Arnaldo > Patch 3/13 - 6/13 are improved according to Arnaldo's suggestion: Some > lines are made compat, return values of strdup() are checked, use > named initializers.
