You're not meant to have such variables set when running build-many-glibcs.py, and can definitely expect additional warnings with -O1 or -O3, for example. (We *should* fix things to build cleanly with -O1 and -O3 and -Os and -Og, and even -O0, but that's a separate issue.) -- Joseph S. Myers joseph@codesourcery.com
