Underscores seem to have wrong syntax table entry

[Tim V. H. <tim...@an...>]

Currently (CVS emacs, daily builds at approx. 8am CET), cc-mode does not
consider underscores to be word components.  This never gave me problems,
in fact it was occasionally useful that forward-word and backward-word
jumped to 'words' within identifiers.  However, for a programming language,
identifiers ARE the words, so underscores need to have word syntax ('_' by
itself is even a valid identifier).
In particular, a replace-regexp of \<long\> (e.g. by int32_t) should 
replace all
occurrences of the word "long", and nothing else.  This means that, say,
"long_answer" should be left alone.  Currently this is not the case, 
which made
so replacements in large files a much bigger pain than it should have been.
