cxref-cpp - A modified C preprocessor to use with cxref.
To improve the output that is available for the source code for cross-referencing a modified version of the GNU CPP v2.7.2 is supplied (named cxref-cpp). This modified C preprocessor allows for a finer control over some features of the preprocessing that are not important for a compiler. In a standard preprocessor, the preprocessor directives are intended for use only by the preprocessor, so passing the information through is not important. With cxref-cpp, there are some features that are different to the standard GNU CPP: Compared to gcc versions earlier than version 2.8.0 there is an extra option that will output the #include lines from the source file. In version 2.8.0 and later this option is present. Comments trailing a #include or a #define are not preserved by all versions of gcc even if the -C option is used. This is not important while compiling, but is useful for documenting. The cxref-cpp program will take on the personality of the installed version of gcc so that the gcc header files can be parsed. This means that it includes the same default include directory paths and macro definitions. The file that contains these definitions is called cxref-cpp.defines and is installed by the cxref-cpp- configure program or specified by the -cxref-cpp-defines command line option.
The same as for gcc, apart from '-cxref-cpp-defines' described above.
