Well, as I said I doubt whether Emacs has the problem, but it could be something 
like this:

a/x.h: #include "y.h"
b/z.h: #include <x.h>
b/y.h: int foo;
c/y.h: char foo;
c/f.c: #include <z.h>

cd c; cc -I../a -I../b f.c

With GNU, 'foo' is of type 'int'. With Microsoft C, it sounds like 'foo' is of 
type 'char'. I don't use Microsoft C so this example is untested there and may 
not be quite right, but I hope it gives you the idea.
