I do not have any optimization flags, although while i do use ccache i am able to reproduce this by disabling it in src.conf. i also am not seeing any reports of functions not being declared, although i'm currently re-testing the build now with a single worker passed to make so that i can get clearer output to validate this. i'm also going to try on another box running current i have to see if this is just my laptop being silly or if there is a real issue. cheers, -pete -- Pete Wright pete@nomadlogic.org @nomadlogicLA
