Or rather, nobody until now built with such an old version to find all problems that need to be worked around if possible, or the new (lowest version to support) oldest version to give up on, where the maintenance yield is too low... People had problems finding systems with gcc as low as 4.1.x, for which problems have recently been solved. I wouldn't be surprised if a detailed bug report would help making 3.4.x supported at least for native bootstrap... Maybe person or persons with such access could help finding the right set of casts, which for gen* programs might be cold enough to minimize the maintenance burden from uglification. brgds, H-P
