Comment (by eschnett):

 #define does not have name scopes. If E is defined, we assume it comes
 from Kranc, and redefine it to its proper value with vectorisation (i.e.
 with ToReal). If it is not defined, then we don't define it here either.

 If we #define E here unconditionally, and some code tries to use it as a
 variable/type name, then this will fail. This would insert the identifier
 E into all source code, even those not using Kranc.
