+Apr 7, 1998:
+ The interface between toplev.c and the language front ends for opening the
+ source file has changed:
+
+ o init_lex() has been renamed to init_parse (char *filename) where filename
+ is the name of the source file.
+ o The code in toplev.c which opened the source file should be moved to
+ the new init_parse function.
+ o toplev.c now calls finish_parse() instead of closing the source file
+ using fclose(). This should now be done in finish_parse, if necessary.

Front-ends must now define lang_print_xnode. It is safe for this
function to do nothing. See c-lang.c.
