[ I believe this is a solution in search of a problem, but the ongoing
discussion in comp.lang.c and comp.lang.c++ indicates that lots of
people are interested in something like this. /r$ ]
Here is a very simple program I wrote after seeing the recent
controversy in comp.lang.c++ over "multiple inclusion". It just puts
#if FILENAME != 0
#define FILENAME 0
at the top of each file (if the -i option is specified) and puts
#endif /* FILENAME */
at the bottom. The -o option does likewise, but it puts the macros around
all the #includes:
#include "foobar.h"
goes to:
#ifndef FOOBAR_H
#define FOOBAR_H 1
#include "foobar.h"
#endif /* FOOBAR_H */
