Only two things to add: you forgot to add `cachedump.o' to the list of
OBJS in the utils/adt Makefile.

You should probably make `isdirty' the last member of this struct, so as
to reduce alignment/padding requirements (this won't actually save any
space right now, but it might save some space if more members are added
to the struct in the future).
