--- Comment #33 from Sergey Fedorov <vital.had at gmail dot com> --- (In reply to Eric Gallager from comment #31) Ever since I came across a couple of instances suggesting some (very limited) support for blocks in Apple gcc-4.2. So you are right. This does not help us much though, unfortunately, since that support appears rudimentary and, importantly, won’t work with C/C++11, (For the same reason Plausible Blocks compiler won’t be of much use, even if it can work as claimed.)
