 serve as a repository for information on these interface and any incompatable
 changes we've made.
 
+Aug 31, 1998:
+  The interface to HANDLE_PRAGMA has changed.  It now takes three arguments.
+  The first two are pointers to functions that should be used to read characters
+  from the input stream, and to push them back into the input stream respectively.
+  The third argument is a pointer to a null terminate string which is the first
+  word after #pragma.  The expression supplied by HANDLE_PRAGMA should return
+  non-zero if it parsed and implemented the pragma.  Otherwise it should return
+  zero, and leave the input stream as it was before the expression was evaluated.
+
+  A new back-end definable macro has been added: INSERT_ATTRIBUTES.  This macro
+  allows backend to add attributes to decls as they are created.
+
+Jun 10, 1998:
+  The interface to lang_decode_option has changed. It now uses and argc/argv
+  interface to allow for options that use more than one input string. The new
+  declaration is: int lang_decode_option (int argc, char** argv). It now
+  returns the number of input strings processed, or 0 if the option is
+  unknown.

 Jun  7, 1998:
   Front-ends must now define lang_init_options.  It is safe for this
   function to do nothing.  See c-lang.c.
