I've applied this patch to update c99status.html after the publication of
C99 TC3.

I've applied this patch to update c99status.html regarding the status of
VLAs and stdint.h. Although there are some technical issues for VLAs
remaining for which I've filed the listed PRs, I think listing them as
"Done" is now fair as these corner cases are unlikely to be found in
ordinary code.
