The details needed for comments must all be defined in the
originating major mode, or have some corresponding override value
that semantic can use.

In your originating major mode, if you can use (forward-comment 1)
then the semantic will also be able to ignore your comments.

If you do not have, or wish to have a major mode, then you can instead
set the variable comment-start-skip and tweak the
semantic-lex-syntax-modifications according to major mode rules.
After this, you must make sure that `semantic-lex-init' is run.  If
you do those changes in your setup function then the rest of the
harness will find them and use them.

In your originating major mode, if you can use (forward-comment 1)
   then the semantic will also be able to ignore your comments.

This doesn't appear to be the case necessarily, in since the file
consisting of one comment

 /* ignore */

withmy simple-mode.el as in the mail I just sent, 
M-: (forward-comment 1) works, but M-x bovinate produces only
the message

simple-lexer: Unmatched Text during Lexical Analysis

   If you do not have, or wish to have a major mode, then you can
   instead set the variable comment-start-skip and tweak the
   semantic-lex-syntax-modifications according to major mode rules.
   After this, you must make sure that `semantic-lex-init' is run.
   If you do those changes in your setup function then the rest of
   the harness will find them and use them.

I'm surprised by the above result, and I do have a major mode, but
I can try working along these lines too... though any feedback
on why the other route isn't working would be helpful.
