This seems likely, for example:
--- foo.h ---
#define abs(x) ((x)<0?(-(x)):(x))
...
--- cepread.c ---
#include "foo.h"
#include <stdlib.h>
...

This would generate an error, because the compiler would be given:

int ((int _i)<0?(-(int _i)):(int _i));

I think the general solution here is to always make sure you include
standard header files before your own non-standard ones.
