-- There are two kinds of FP_CONTEXT for this architecture, corresponding
-- to newer and older processors. The type is defined in fppI86lib.h as a
-- union. The form used depends on the versions of the save and restore
-- routines that are selected by the user (these versions are provided in
-- vxwork.ads). Since we do not examine the contents of these objects, it
-- is sufficient to declare the type as of the required size: 512 bytes.
