+/* Platform specific #defines to be shared by the various platforms sharing 
+*  the unixish_86 code
+*/
+
+/*
+*  The goal here is to clearly define the binary compatibility parameters for
+*  the platforms that will use this code. Rather than switch at compile time
+*  based on the compiler that happens to be in use we are forcing implementors
+*  to make a conscious decision.
+*
+*  For some of these platforms the community may choose to have more than one
+*  binary model in effect. In that case I suggest that there be explicit sub
+*  defines for that platform specifying 'TYPE1', 'TYPE2', etc. The decision on
+*  which 'TYPE' to use would be triggered by a setting passed through from the 
+*  config system.
+*
+*  For example we might end up with something like:
+*
+* #elif defined(NTO) 
+* #  if defined(TYPE1)
+* #    define CFRONT_STYLE_THIS_ADJUST
+* #  elif defined(TYPE1) 
+* #    define THUNK_BASED_THIS_ADJUST
+* #  else
+* #    error "need TYPE1 or TYPE2 for NTO"
+* #  endif
+* #elif defined(__BEOS__) 
+*
+*  and so on....

+ * 5.x, /usr/src/contrib/gcc/config/freebsd.h explicitly undef's
+ * DEFAULT_VTABLE_THUNKS.  (The one exception is a brief period (September
+ * 1999 - Jan 2000) during 4.0-CURRENT, after egcs was merged --
+ * this was changed before 4.0-RELEASE, but we can handle it anyway.)
+ *
+ * Versions of gcc from the ports collection (/usr/ports/lang/egcs),
+ * however, have DEFAULT_VTABLE_THUNKS #defined to 1, at least
+ * in all ports collections since the 2.95 merge.  (Supporting optional

+ *
+ * The easiest way to distinguish the ports collection gcc from the system
