Fair enough. Suffice it to say that it's definitely confusing, though, given the datapoint that I was very confused! :) And it sent me off on rather a wild goose chase through the GNU ld manual trying to figure out why alignment wasn't working right (on an older pre-33721-fix version of GCC). Is there useful documentation of the relevant file formats that could be pointed to instead?
