That is not completely right. Sorry. Under "To import a new release:" it
has slightly more accurate instructions. You want to skip the importing
into the svn branch. But this part is essential:

- Check out a classpath snapshot or take a release tar.gz file.
  I use 'cvs export' for this.  Make a tag to ensure future hackers
  know exactly what revision was checked out; tags are of the form
  'libgcj-import-DATE' (when using a tagged checkout do:
  - ./autogen.sh && ./configure && make dist
  to get a proper .tar.gz for importing below).

You want to use a real release version (as produced by make dist) since
that might contain some generated files that are not in pure CVS.

standard.omit is a generated file now (it used to be in CVS). If it is
not in the classpath tree then use the current one from
gcc/libgcj/classpath/lib/standard.omit which lists:
gnu/test/.*java$
gnu/java/awt/peer/x/.*java$

Cheers,
