[illumos-Advocates] [RTI] 1222-1224, 1230 constant string overwrites and GCC4.x stdarg

[Richard Lowe]

Ok, my problems appear to have been pre-existing.


 - one is due to #1279, and a prior change of mine which the shadow
compiler missed, since it only shadows files compiled to intermediate
objects.)

 - One is a warning from libdwarf, which I was concerned the
builtin-in switch triggered (and then concerned my libdwarf changes
triggered!), but appears to have pre-existed all of this, but been
missed because it doesn't land in the mail_msg noise.

I'd like to go ahead and integrate the wad as RTId above (I plan to
ask for review for #1279 next, I think).
