Does migrate.c simply not refer to anything which these headers provide? Or does migrate.c already pick up these headers via nested includes? If the latter then that can be a problem - build breakage under rare configs, or as code generally evolves. Not a *big* problem - we detect and fix such things quickly, but I do think general good practice is to directly include whatever the .c file requires.
