First, 'M-;' make a c style comment in a new line in a .h file, it prints  
'/*   */', and the cursor blinks at the 2nd space char.

Then, 'M-J' to run 'c-indent-new-comment-line', and it gives
'/*
  *  */' and the cursor blinks at the last '*', but I think it should be  
blinks at the 2nd space in the second line.

Please point out if I am wrong or have missed something.

Thanks!

Yes.  This is the place where you'll be wanting to start typing.

More precisely, you get this (but not in gnu style - use C-. k&r first to
see this):

/*
 *  */
    ^
    |
  point

What you are saying, it I understand you correctly, is that you should
see this:

/*
 *  */
   ^
   |
 point

I agree with you.  It's a bug.

> Please point out if I am wrong or have missed something.

c-indent-new-comment-line is a rat's nest of special cases.  Invoking it
when there's no text inside the "/*  */" needs special handling.

I'll fix it.

But why 3 spaces?  This looks like a bug.  But when I try it in Emacs -Q,
I get 2 spaces, so maybe it's something in his .emacs ?

Maybe.  Maybe he copied the string by hand, and an extra space slipped
in.  

William, if you suspect that you got one space too many in '/*   */',
please dump your CC Mode configuration (with C-c C-b) and post it here.

I think the essence of this bug is that point ends up further to the
right after the M-j that where it started.  An M-j should NEVER do this -
normally, of course, point ends up at the far left, just after the
comment prefix.

I've committed a fix to ..../progmodes/cc-cmds.el.  Could you update your
Emacs and try it out, please.

There are only 2 spaces here also. Maybe I added one more space  
accidentially when writing the message, sorry.

It seems not to work, even start emacs with -Q.

When did you commit the fix? I made a update about 12 hours ago and now  
there is nothing newer.
Here is the information of 'c-c c-b', maybe it can help something.

Revision 1.54 of .../progmodes/cc-cmds.el, about 8 hours ago, at ~22:30
GMT.  I've just had a look at http://savannah.gnu.org, and it's
definitely there now.
