changes we've made.
-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.

-Apr 1, 1998:
- Front-ends must now define lang_print_xnode. It is safe for this
- function to do nothing. See c-lang.c.
+2001-02-26:
+ A DECL_INITIAL of NULL_TREE or error_mark_node in a VAR_DECL is no longer
+ taken to signify a tentative definition which should not be emitted until
+ end-of-file. Frontends which want that behavior should set
+ DECL_DEFER_OUTPUT before calling rest_of_decl_compilation.
Feb 1, 1998:
When a size in bits is converted into a size in bytes, which is expressed
in trees, care should be taken to change the tree's type again to sizetype.
- We've updated C, C++, Fortran & Objective-C to work with the new
- scheme. Other languages will need to be updated accordingly.
- Contact amylaar@cygnus.com for additional information.

?? 1997:
In an effort to decrease cache thrashing and useless loads we've changed the
third argument to the DEFTREECODE macro to be a single char. This will
- effect languages that defined their own tree codes (usually in a .def file).
