Well, given the source file from Tom Hughes, ie

  #ifndef __cplusplus
  #include <stdbool.h>
  #endif
  #include <stdio.h>
  
  int main(int argc, char **argv)
  {
    printf("%d\n", sizeof(bool));
  
    return 0;
  }

Compiling on RISC OS with gcc 2.95.2 gives

  ADFS::Primary.$.Public* gcc test.c
  ADFS::Primary.$.Public* !RunImage
  4
  ADFS::Primary.$.Public* g++ test.c
  ADFS::Primary.$.Public* !RunImage
  1

I suspect that people have got away with it for so long because
bool doesn't appear in many structs.  One rare example is with
drawfile_options, in the file drawfile.h.  For the file

  #include <stdio.h>
  #ifdef __GNUG__
    #define bool dummy
    #include "types.h"
    #undef bool
  #endif
  #include "drawfile.h"
  
  int main()
  {
    printf("%d\n", sizeof(drawfile_options));
  
    return 0;
  }

Using c++ gives 76, but using g++ gives only 60.  So, as Jonathan
says, we (you) have to do something.
