I have a small lisp utility that might help; dwimtab (see doc later
in this posting). It doesn't automagically line up record declarations,
but it's a step on the way. I've used it in C, C++, Java and Ada mode. 
Mail me if you want the source.

Do-What-I-Mean tab. This function uses the original keybinding for the
TAB key when it is used (e.g. c-indent-line). If this does not change
the position of the point, an attempt is made to position the point
under the next 'interesting' point in the first non-blank line above
the current line. An interesting point is a start of a new column
(signified by multiple whitespace), a ':' or a '='. If no interesting
point is found, a tab-to-tab-stop is performed. This sounds weird but
it is of good use if one wants to line up declarations like:

  VeryLongTypeName  VeryLongVariableName = VERY_LONG_CONSTANT;
  int               Count                = 0;
  char *            Str                  = (char *)NULL;

A single TAB is required between ('int' - 'Count'), ('Count' - '=')
etc.  To add this feature to your favourite major mode (e.g. c-mode),
put this file in your load path, compile it and place this in your
.emacs:

(autoload 'dwimtab-tab "dwimtab")
(add-hook 'c-mode-hook 
  (lambda () (define-key c-mode-map "\t" 'dwimtab-tab)))
