The generated code is for now *unconditional*. Later patches generate
the conditionals.

+Where a member can be defined with a single string value for its type,
+it is also possible to supply a dictionary instead with both 'type'
+and 'if' keys. (TODO: union and alternate)
+
+Example: a conditional 'bar' member
+
+{ 'struct': 'IfStruct', 'data':
+ { 'foo': 'int',
+ 'bar': { 'type': 'int', 'if': 'defined(IFCOND)'} } }
+
An enum value can be replaced by a dictionary with a 'name' and a 'if'
key.
