A walker that creates an AST. All Translate* methods have been overridden to remove the translation code.

Sets extract tails to true. This will cause the parser to create dummy declarations for comments before close braces or the end of the file

Sets store links to true. This will cause the whole ptree to be traversed, and any linkable identifiers found will be stored

Returns a formatter string of the parameters. The idea is that this string will be appended to the function name to form the 'name' of the function.

The state of postfix translation. This is needed for constructs like foo->var versus var or foo->var(). The function call resolution needs to be done in the final TranslateVariable, since that's where the last name (which is to be linked) is handled.

Finds the column given the start ptr and the current position. The derived column number is processed with the link_map before returning, so -1 may be returned to indicate "inside macro".

A pointer to the current template parameters, if any, used to get the template parameters and set in the declaration. Should be NULL if not in a template.

This pointer is used as a comparison to avoid redundant effort. Do not use it to get the filename, since the string is a reference to the preprocessed file in memory and is *not* null terminated!

Storage for links. This is only set if we should be storing links, so it must be checked before every use

The params found before a function block. These may be different from the ones that are in the original declaration(s), but it is these names we need for referencing names inside the block, so a reference is stored here.

The Scope to use for name lookups, or NULL to use enclosing default scope rules. This is for when we are at a Variable, and already know it must be part of a given class (eg, foo->bar .. bar must be in foo's class)

foo->var versus var or foo->var(). The function call resolution needs to be done in the final TranslateVariable, since that's where the last name (which is to be linked) is handled.
