Comment syntax folding is included by default in the c.vim syntax file.

Do you want to make a 10-line /*C-style*/ comment disappear?
You can add folding capability to C-style comments using the command:
au BufNewFile,BufRead *.cpp,*.c,*.h,*.java syn region myCComment start="/\*" end="\*/" fold keepend transparent
This will work on C, .h, C++, and Java files.
The "keepend" and "transparent" commands are necessary to avoid overriding the default syntax highlighting of comments.
If you want to keep the "/*" beginning of the comment in the folded text, you can use the following function:
set foldtext=MyFoldText()
function MyFoldText()
let line = getline(v:foldstart)
let sub = substitute(line, '^[\t ]*', '', '')
let nlines = v:foldend - v:foldstart + 1
if strlen(nlines) == 1
let nlines = " " . nlines
elseif strlen(nlines) == 2
let nlines = " " . nlines
endif
return "+-" . v:folddashes . nlines . ": " . sub
endfunction
The resulting line should look about the same as the default, without removing the comments.
