gcc c++ option

[William Estrada]

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; }
