Note: you can't set -Wno-implicit-function-declaration globally for the whole bootstrap, otherwise some configure tests will end up failing when they check if functions are declared. If this was the stage1 failure, I've tackled that by simply building 3.7.8. Version in tree is also 3.7.8, so that should work too. |
