Pull Request Summary

Closes #32

Description

When the improved numerics for IC4 was added, some #ifdef WW3_IC4 statements were replaced with #ifndef W3_IC4_NUMERICS, which is incorrect. The correct line is :

#if defined(W3_IC4) && !defined(W3_IC4_NUMERICS)

So that builds without W3_IC4 are possible

Issue(s) addressed

#32

Commit Message

Add #ifdef W3_IC4 where required to support building without W3_IC4 set
