What I was trying to say was I changed a header file that is unaffected by a
macro and obviously included...see below, however...

Now that I slept on it, that's probably what happened. Awhile back we did add
some changes that conditionally include entire files based on a macro. But
it's of the form

#include file1
#include file2

which didn't immediately match the pattern above in my brain ;-)

No, haven't seen that....
