How to convert my C source code to standard C source code

[sjhawar]

I wonder if there exists some software that inputs a C file and outputs a standard C-file. I would like to convert my C source code (automatically generated by a 16-bit translator to C) to standard C source code so that it includes only standard C header files. My C source coding includes CB.h, which is not an ANSI C standard C header file. My C source code is 100% accurate as it compiles fine and creates the .exe file using Microsoft Visual Studio 2015. Because of the CB.h header file, my C source coding mostly contains keywords starting with _mb (example: _mbprnt instead of printf).
