with-compilation-unit records non-local control transfers and
arranges for summarize-compilation-unit to report them to *error-
this can cause a thread to emit spurious output if an application
terminates a compile call for good cause or if it provides its own
facilities to record and report compilation errors.
would there be some reason to not add *compile-verbose* to the
preconditions for summarize-compilation-unit's report?
if that is not appropriate, is there some other method to suppress
