--- Comment #32 from Sergey Fedorov <vital.had at gmail dot com> --- (In reply to Iain Sandoe from comment #30) > blocks have support from 10.6 [Apple gcc-4.2] (although there is/was 'after > market' support for 10.5). So blocks presumably should work in Rosetta then? Or the support is still Intel-only?
