C/C++ preprocessor expands macros and processes '#if', '#include' and some other directives. MCPP is an alternative C/C++ preprocessor with the highest conformance, implementated by Kiyoshi Matsui. It supports multiple standards: K&R, ISO C90, ISO C99, and ISO C++98. MCPP is especially useful for debugging the source program which use complicated macros and also useful for checking portability of the source. Though mcpp could be built as a replacement of GCC's resident proprocessor or as a subroutine called from some other main program, this package installs only a stand-alone program named 'mcpp' which behaves independent from GCC.
