DBus module foreign function warnings

[Jerry J. <log...@gm...>]

Greetings,

While compiling mercurial head (34f69a3fbf80) on an x86_64 Fedora
Rawhide machine with dbus 1.12.0, I get the following warnings when
building the dbus module:

;; Loading file /builddir/build/BUILD/clisp-2.49.60/build/dbus/dbus.fas ...
WARNING: FFI::FIND-FOREIGN-FUNCTION: foreign function
         "dbus_message_set_serial" does not exist
         Skip foreign function creation
WARNING: FFI::FIND-FOREIGN-FUNCTION: foreign function "dbus_message_lock" does
         not exist
         Skip foreign function creation
WARNING: FFI::FIND-FOREIGN-FUNCTION: foreign function

         Skip foreign function creation
;; Loaded file /builddir/build/BUILD/clisp-2.49.60/build/dbus/dbus.fas

All 4 functions do exist in libdbus-1.so, according to readelf.  There
are prototypes for the first 3 in dbus-message.h, and in
dbus-connection.h for the last one.   Is this something I should worry
about?  Is there some way of determining why clisp thinks those
functions don't exist?

Thanks,
