order of includes?

[Brian Budge]

Hi all -

I am getting the following error:

error: expected `,' or `...' before numeric constant

The code is trivial, and has been successfully used before.  It is
from a template library I wrote.

From searching google, I get the impression that it could be from
#including things in the "wrong" order.  Could this be the case? 
Anybody have any tips or tricks for narrowing down the problem here?

Thanks,
  Brian
