Under the recently released GCC 2.95 (using g++) this code:
GnomeUIInfo info =
{
GNOME_APP_UI_ITEM, N_("_New game"), N_("Create a new game"),
onMenuFile, reinterpret_cast<gpointer>(0), null,
GNOME_APP_PIXMAP_STOCK,
GNOME_STOCK_MENU_NEW, // ERROR
'n', GDK_CONTROL_MASK, null
};
now yields this error:
initialization to `void *' from `const char *' discards qualifiers
This is because GNOME_STOCK_MENU_NEW is a macro define for a "string"
literal, which is const, and is being used to initialize a void*.
Notwithstanding complaints of bad design and programming style, to fix
this I have to perform a const_cast:
const_cast<char*>(GNOME_STOCK_MENU_NEW), // OK
I also now have problems with the prototype for destroy callbacks being
untyped:
void (*)(...)
Notwithstanding complaints of bad design and programming style, this
suppression of the compiler's type system now causes some of my
overloaded functions to choke. To fix this, I had to change the names of
some of them.
I suppose my question is: will GNOME ever be type safe and sound? Are
there any other GCC 2.95 pitfalls I should be aware of?
