It accepts \fBcpp\fR(1) style options and arguments. \fBmsgcpp\fR preprocesses an input C source file and emits keyed lines to the output, usually for further processing by\fBmsgcc\fR(1). \fBmsgcc\fR output is in the \fBgencat\fR(1) syntax. Candidate message text is determined by arguments to the last \fB\fR and \fB\fR functions.

This enables non-C semantics. All source should first be compiled error-free with a real compiler before running \fBmsgcpp\fR. The following changes are enabled for the top level files. Included file behavior is not affected. +.RS +4 +.TP +1. +All \fB#if\fR, \fB#ifdef\fR and \fB#ifndef\fR branches are enabled. +.RE +.RS +4 +.TP +2. +The first definition for a macro is retained, even when subsequent \fB#define\fR statements would normally redefine the macro. \fB#undef\fR must be used to redefine a macro. +.RE +.RS +4 +.TP +3. +Macro calls with an improper number of arguments are silently ignored. +.RE +.RS +4 +.TP +4. +\fB#include\fR on non-existent headers are silently ignored. +.RE +.RS +4 +.TP +5. +Invalid C source characters are silently ignored. +.RE +.sp +.LP +\fBmsgcat.h\fR is included if it exists. This file may contain macro definitions for functions that translate string arguments. If \fBfoo\fR is a function that translates its string arguments then include the line \fB#define foo _TRANSLATE_\fR in \fBmsgcat.h\fR, or specify the option \fB-Dfoo=_TRANSLATE_\fR. If \fBbar\fR is a function that translates string arguments if the first argument is \fBstderr\fR, then use either \fB#define bar _STDIO_\fR or \fB-Dbar=_STDIO_\fR. +.sp +.LP +The macro \fB_BLD_msgcat\fR is defined to be \fB1\fR.
