I can confirm the OP's observation on Emacs 23. Running emacs -Q and
opening a .c file, with a code snippet like the following:

  int minrow, mincol, majrow, majcol, i; /*counters*/
  int inputvalue, outputvalue, changecount;

  changecount = 0;

The declaration rows are nicely coloured, but the following line
('changecount = 0') is not. Variable names in the declaration lines are
subject to font-lock-variable-name-face, while the variable name outside
of the declaration is given the default font. So, at least on my setup,
you can modify the font-lock for declarations, but not for subsequent
occurrences of the variable (or function). At least, not without some
further modification of the color-theme.
