gcc c++ option

[William Estrada <MrUmunhum at popdial dot com>]

Hi folks,

 I have a question about where this is a bug or not?

 It seems that gcc all ways turns __cplusplus true even when you only include
.c and .h input files?  Does this seem wrong to you all?

 If you can see a problem, please let me know.  Here is a set of test file:

/* global.h ---------------------------------------------------------------- */

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <ctype.h>

#ifdef __cplusplus
extern "C" {
#endif
 
char   stuff[50];
int    RC;
int    sub1();
int    sub2();
 
#ifdef __cplusplus
}
#endif

/* global.c ------------------------------------------------------------------ */

#include "global.h"

int main( int argc, char **argv )  {

 printf("\n");
 
 if( argc > 1 ) {
   strcpy(stuff, argv[1]); }

 printf("%10s %3d Stuff = '%s'\n", __FILE__, __LINE__, stuff);
 
 RC = sub1();
 printf("%10s %3d Stuff = '%s' RC = %d\n", __FILE__, __LINE__, stuff, RC );
 
 RC = sub2();
 printf("%10s %3d Stuff = '%s' RC = %d\n\n", __FILE__, __LINE__, stuff, RC );

 return 0; }

/* subs.c ------------------------------------------------------------- */

#include "global.h"

int
sub2() {
 strcat( stuff, ", Sub2 hello" );
 printf("%10s %3d Stuff = '%s'\n", __FILE__, __LINE__, stuff);
 return 99; }

int
sub1() {
 strcat(stuff,", Sub1 Here");
 printf("%10s %3d Stuff = '%s'\n", __FILE__, __LINE__, stuff);
 return 1; }
