Please include the text of documentation for new hooks in target.def
instead of tm.texi.in where possible (so tm.texi.in just has the @hook
line) - that is, unless it's based on older GFDL-only text.
A lot of the new source files appear to include toplev.h but I don't see
any uses of functions declared there. I cleaned up toplev.h includes last
year; please make sure that source files only include headers they
actually need.
