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.

Front ends which link with c-common or other files from the C/C++
front-ends may need to handle TI types. Look for references to
