The error messages are of this form:

```
/usr/include/x86_64-linux-gnu/bits/mathcalls.h(316): Error: 
illegal combination of type specifiers
/usr/include/string.h(43): Error: found `__dest` when expecting 
`,`
```

I was only able to identify the offending lines by repeatedly 
commenting and uncommenting code.
