This is because lots of files include this # *generated* file and if it doesn't exist when we generate the deps it is no # good. There's a -MG compiler option to cover for this case, but it doesn't # play nicely into this as it then adds a dependency to the lang.h file # without the proper path. # # The trailing sed hack for a range of files is present because how gcc works # for generating dependencies when the include file doesn't exist. Then it # makes the dependency without any path, and that breaks how things work for # us.
