John Marino <gnugcc at marino dot st> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |gnugcc at marino dot st --- Comment #4 from John Marino <gnugcc at marino dot st> --- I hit this last night. Classifying it as "unfortunate" is an understatement. There's nothing consumers can do about it there's no states policy to maintain the ability for the next GCC to build the previous one, but A) there probably should be such a policy and B) hopefully even without policy this situation should be actively and vigorously avoided. So in the past, this worked: 5 -> 4.9, 6 -> 5, and 7 -> 6 I was expecting 8 -> 7 (at least) to also work. Disappointed that this is a "WONTFIX" but apparently there's no simple fix.
