| # This BUILD_CONFIG option is a bit like bootstrap-debug, but rather | |

| # This makes it slower than bootstrap-debug alone, for there's | |
| # additional dumping and recompilation during stage3. | |
| # bootstrap-debug-big can avoid the recompilation, if plenty of disk | |
| # space is available. | |
