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 implements 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
       compiler-independent-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:

       -@MODE Specify preprocessing mode. MODE should be one of these 4:

	   -@std
	      Standard conforming mode. (default)

	   -@poststd, -@post
	      special 'post-Standard' mode.

	   -@kr
	      K&R 1st mode.

	   -@oldprep, -@old
	      "old_preprocessor" mode (i.e. "Reiser model" cpp).

       -C     Output also comments.

       -D <macro>[=<value>]
	      Define <macro> as <value> (default:1).

       -D <macro(args)>[=<replace>]
	      Define <macro(args)> as <replace>.

       -e <encoding>
	      Change the default multi-byte character encoding to one of: euc_jp, gb2312, ksc5601, big5, sjis, iso2022_jp, utf8.

       -I <directory>
	      Add <directory> to the #include search list.

       -I-    Unset system or site specific include directories.

       -j     Do not output the source line in diagnostics.

       -M, -MM, -MD, -MMD, -MP, -MQ target, -MT target, -MF file
	      Output source file dependency line for makefile.

       -N     Don't predefine any non-standard macros.

       -o <file>
	      Output to <file>.

       -P     Don't output #line lines.

       -Q     Output diagnostics to "mcpp.err" (default:stderr).

       -U <macro>
	      Undefine <macro>.

       -v     Show version of mcpp.

       -W <level>
	      Set warning level to <level> (OR of {0,1,2,4,8,16}, default:1).

       -z     Don't output the included file, only defining macros.

       Options available with -@std (default) or -@poststd options:

       -+     Process C++ source.

       -2     Enable digraphs.

       -h <n> Re-define the pre-defined macro __STDC_HOSTED__ as <n>.

       -S <n> Redefine __STDC__ to <n>, undefine old style macros.

       -V <n> Redefine __STDC_VERSION__ or __cplusplus to <n>.
	      C with -V199901L specifies C99 mode.
	      C++ with -V199901L specifies C99 compatible mode.

       Options available with only -@std (default) option:

       -@compat
	      Expand recursive macro more than Standard.

       -3     Enable trigraphs.

       -K     Embed macro annotations into comments.

       Options available with -@std (default), -@kr or -@oldprep options:

       -a     Process "assembler" source.

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:
		  token expand macro_call path if expression memory getc

       #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
	      Putout warning "any message".
