Sorry, I don't understand why it should be difficult or what makes more 
difficult to handle this file that, for instance tramp or cc-mode.

Wouldn't it better to keep one verilog-mode.el version in ELPA 
fully compatible with Emacs-21?
And let the file in the master branch to benefit of all that
has come since Emacs-21?

I also notice that the file is very large (> 14 klines).
Maybe it would be easier to maintain if the file is split in 4-5 files.
