Re: WO4: WOApplication.h/interpreter.h (re)definition of 'trace'

[David Neumann <dneumann@apple.com>]

Right. Right. I've hit this myself when building my Java Wrappers. Lame.
Ok.  If you modify WOApplication.h by placing this line

#undef trace

near the top, say, below these imports...
#import <Foundation/NSDate.h>
#import <Foundation/NSString.h>
#import <Foundation/NSLock.h>


That problem should safely go away.
