Do we have a feeling on which aspects of 32-bit cause us the support burden ? The boring stuff like compiler errors from mismatched integer sizes is mostly quick & easy to detect simply through a cross compile. I vaguely recall someone mentioned problems with atomic ops in the past, or was it 128-bit ints, caused implications for the codebase ?
