I'm working with the allegro GUI system and recieve this error message when
compiling with the C++ compiler:

"initialization to 'void *' from 'const char *' discards qualifier"

It places the line numbers for the errors at the end of each DIALOG array,
i.e. the following gets one:


DIALOG file_save_dialog[] =   {
   { d_shadow_box_proc, 80,   32,   300, 70,    255,  0,    0,       0,
0,   NULL,  NULL, NULL  },
   { d_box_proc,      92,    47,   272,  12,   255,  0,    0,       0,
0,   NULL,  NULL, NULL  },
   { d_edit_proc,     93,    49,   270,  12,   255,  0,    0,       0,
80,   0,    "Filename",       NULL, NULL  },
   { d_button_proc,    120,  70,   100,  18,   255,  0,    'o',  D_O_K,
0,   0,    "&Ok",     NULL, NULL  },
   { d_button_proc,    230,  70,   100,  18,   255,  0,    'c',  D_CLOSE,
0,   0,    "&Cancel",     NULL, NULL  },
   { NULL,              0,    0,    0,    0,    0,    0,    0,       0,
0,   0,     NULL }
   };

I would guess that some type of casting is required, but I can't figure out
where.  These errors are also accompanied by warnings stating "converting
NULL to non-pointer type".  Anyone know how I can get the GUI stuff to
compile right under C++?

Thanks
