There have been a couple of review submissions so far, so at this
point I will keep the review on track for its normal ending period,
thus it ends tomorrow night. I will go through the reviews and create
an overall summary shortly thereafter (I already have time set aside
for Tuesday for this).

Do note, thus far there have been a few issues brought up about this
library, I will see how these continue, but you may expect me to ask
for feedback on them as there seems to be a possible conditional
acceptance for this library, and at least one (gcc related) bug-fix
due to how this library implements something that is not well defined
in the standard.

If at all possible, please finish up discussion soon, but do not feel
rushed, I can delay the final decision, this is an important library
for older compilers and it needs to be very well fleshed out.
