Here's just one example what will happen, when STRICT_OPENSTEP is
defined:
In file included from
/opt/GNUstep/System/Headers/AppKit/NSApplication.h:32,
from NSApplication.h:52,
from NSApplication.m:49:
/opt/GNUstep/System/Headers/AppKit/NSResponder.h:44:
error: parse error before "NSInterfaceStyle"
In file included from NSApplication.h:52,
from NSApplication.m:49:
/opt/GNUstep/System/Headers/AppKit/NSApplication.h:34:
error: parse error before "class"
/opt/GNUstep/System/Headers/AppKit/NSApplication.h:81:
error: parse error before "interface"
[...]
And I _did_ report that before.
