TITLE : Using CPP to Resolve Mysterious Compiler Errors
The preprocessor CPP.EXE can be used when you are not sure how
#include is working, how #define macros are being expanded or how
the various #if directives are being evaluated, among other
things. The default CPP output file name will be the same name
as the input source file with a .I extension.
The output from CPP is often useful when you are getting error
messages during compilation and the reason is not clear when
viewing the source code. If your source code contains complex
macros that take several arguments CPP will show you exactly what
the final expansion will be, which can also be helpful when
trying to find the source of a subtle problem.
