I do this for C mode: (modify-syntax-entry 95 "w" c-mode-syntax-table)

Two problems:
   1) There are comments somewhere that explicitly say "don't do  
this!!!" but I never figured out why.  I'd like to here from others  
why this is not recommended.
   2) There are lots of syntax tables.  Most major-modes have their  
own.  Some minor-modes I think diddle with them too.  Plus there is a  
global syntax table.  So, you will need to explore and figure out  
which syntax tables you want to change.  Then add the modification to  
the appropriate hook(s).

I have this in my .emacs file:

(custom-set-variables
    ...
'(c-initialization-hook (function (lambda nil (modify-syntax-entry 95  
"w" c-mode-syntax-table))))
    ... )
