No, boot_language serves a different purpose. It says that the language itself should be built during stage 1. What I need for Go is to say that C++ should be built during stage 1. That is, boot_language is a yes or no value. I have added lang_requires_boot_language, which takes a list of languages. It is similar to lang_requires, except that it specifically builds the specified languages during stage 1. Ian
