The referenced [patch will enable CFFI running under ABCL to load
jna.jar from Maven repositories over the internetwork][1].

  =----

For most purposes, what the operating environment is executing the
hosted JVM should be irrelevant for users of the implementation.
jna.jar packages native shared objects in a variety of formats, and
has reasonable code for finding the correct implementation to
dynamically link, so for ABCL just defer to the use of
ABCL-ASDF:RESOLVE-DEPENDENCIES.

There seems to be something a little funky with the ABCL JAR-PATHNAME
under ASDF-2.017.22, so we expect to patch for abcl-1.0.1 (within
a month), so we're right on track with you.  How can I test XCVB?

To find what platform the hosted JVM is executing under, I might suggest some variant of 

  CL-USER> (when (find :unix *features* ) (run-program "uname" '("-a")))
