#|
Mini-guide to adding support for deferred warnings on an implementation.

First, look at what such a warning looks like:

(describe
 (handler-case
     (and (eval '(lambda () (some-undefined-function))) nil)
   (t (c) c)))

Then you can grep for the condition type in your compiler sources
and see how to catch those that have been deferred,
and/or read, clear and restore the deferred list.

  "This function provides a portable wrapper around COMPILE-FILE.
It ensures that the OUTPUT-FILE value is only returned and
the file only actually created if the compilation was successful,
even though your implementation may not do that, and including
an optional call to an user-provided consistency check function COMPILE-CHECK;
it will call this function if not NIL at the end of the compilation
with the arguments sent to COMPILE-FILE*, except with :OUTPUT-FILE TMP-FILE
where TMP-FILE is the name of a temporary output-file.
It also checks two flags (with legacy british spelling from ASDF1),
*COMPILE-FILE-FAILURE-BEHAVIOUR* and *COMPILE-FILE-WARNINGS-BEHAVIOUR*
with appropriate implementation-dependent defaults,
and if a failure (respectively warnings) are reported by COMPILE-FILE
with consider it an error unless the respective behaviour flag
is one of :SUCCESS :WARN :IGNORE.
463
If WARNINGS-FILE is defined, deferred warnings are saved to that file.
464
465
466
On ECL or MKCL, it creates both the linkable object and loadable fasl files.
On implementations that erroneously do not recognize standard keyword arguments,
it will filter them appropriately."
