Sorry for the delay.  I do, but am swamped with other things just now.  I hope to get back to this for real in the next couple of days.

Short answer is that I’m fine with most of the changes, except the warning enable.  However, it appears the relevant gcc bug was fixed in gcc4.8 (not sure which patch version):
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=11856

[Note there are quite a few duplicates of that bug too; roughly 10 in total.]

If the warning were enabled conditionally on the gcc version, that would satisfy me.
