Problem conformsToProtocol in class category

[Martin Durkac]

Hi,

I have found out the problem (or incompatibility with OPENSTEP 4.2)
in Foundation with method of NSObject conformsToProtocol.

The following simple program in OPENSTEP (4.2 Intel) 
print out "conforms OK", in GNUSTEP (0.7 - Solaris 2.8 Intel) 
"conforms ERR".

Is it a correct behaviour ???

#import <Foundation/Foundation.h>
#import <stdio.h>

@protocol MyProtocol

- (void) myProtoMethod: (id) aObj;

@end

@interface MyClass : NSObject 
{
}

@end

@implementation MyClass
@end

@interface MyClass (MyCategory) <MyProtocol>
@end

@implementation MyClass (MyCategory)

- (void) myProtoMethod: (id) aObj
{
}

@end

int main (int argc, const char *argv [])
{
    id myObj = [MyClass new];

    if ([myObj conformsToProtocol: @protocol (MyProtocol)])    
        printf ("conforms OK\n");
    else
        printf ("conforms ERR\n");

    return 0;
}
