+2004-09-09:
+ In an effort to decrease execution time, single char tree code
+ classes were changed to enumerated values.
+
+ Old way:
+
+ DEFTREECODE (CLASS_METHOD_DECL, "class_method_decl", 'd', 0)
+
+ New way:
+
+ DEFTREECODE (CLASS_METHOD_DECL, "class_method_decl", tcc_declaration, 0)
+
+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.

+?? 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
+ affect languages that defined their own tree codes (usually in a .def file).
