// DQ (12/3/2020): We sometimes want to read a file twice, and gather the comments

// it can build a file with a different name. So we need to specify the name of the
// file that we want the comments and CPP directives to eventually be attached to 
// and not the one from which they were take.  This technique is used to support
// building a second file to be a dynamic library within the codeSegregation tool.

// AS (012006) Added the function
//     void attachPreprocessingInfo(SgFile *sageFile,  std::map<string,ROSEAttributesList*>*);
// to support reintroductions of macros and fetching of preprocessor directive using Wave. 
// This function does not in itself rely on Wave, but simply takes the same arguement as 
// 'attachPreprocessingInfo(SgFile *sageFile)', but adds an argument std::map<string,ROSEAttributesList*>* 
// which is a map of a pair (filename,list of attributes in that file). The two functions will perform 
// the same tasks in all ways but the way they find the preprocessor directives. In addition to that
// the mechanism here opens up for reintroduction of unexpanded macros into the AST without
// changing the implementation at all. This relies on some external mechanism, that be the 
// Wave preprocessor or some other, to find the preprocessor directives and the unexpanded 
// macros.
