MCPP(1)                        Commands for GCC                        MCPP(1)
NAME
       mcpp - Matsui CPP, an alternative C preprocessor
SYNOPSIS
       mcpp [options] [<infile> [<outfile>]]
DESCRIPTION
       mcpp  is a C/C++ preprocessor with the highest conformance which imple-
       ments C90, C99 and C++98.  mcpp  has  plentiful  diagnostics  and  many
       #pragmas.   It is useful to check portability of your program, and also
       useful to debug complicated macro.  This is a man-page for mcpp of GCC-
       specific-build.
OPTIONS
       mcpp  expects  two file names as arguments, <infile> and <outfile>.  If
       not specified,  <infile>  defaults  to  standard  input  and  <outfile>
       defaults to standard output.
       It takes the following options.
       Commonly used options:
       -$, -fno-dollars-in-identifiers
              Forbid '$' in identifiers.

PRAGMA
       mcpp has the following #pragma directives.
       #pragma once
              Read the header file only once even if multiply #included.
       #pragma __setlocale( "encoding")
              Specify  the multibyte character encoding to "encoding".  See -e
              option for the encodings.
       #pragma MCPP put_defines
              Putout all the macro definitions currently valid.
       #pragma MCPP debug <args>
              Start to putout debugging informations.
                  <args> should be one or more of:

       #pragma MCPP end_debug <args>
              Stop to putout debugging informations.
                  <args> are the same with 'debug'.
                  No argument specifies all arguments.
       #pragma MCPP push_macro( "MACRO")
              Save the macro definition to the stack.
       #pragma MCPP pop_macro( "MACRO")
              Retrieve the macro definition from the stack.
       #pragma MCPP preprocess
              "Pre-preprocess" the following header files for mcpp.
       #pragma MCPP warning    any message
