Compile tests are nice in theory for finding static analysis bugs but
often they introduce static checker false positives because we don't
initialize *param variables in the stub functions.

And those compat stubs in particular were a headache to review.  We
broke the build a couple times, but we *almost* broke the build a *lot*
of times...
