If anyone knows a workaround for the following bug (I have reported it to Apple), I would appreciate knowing about it. I discovered this bug while developing in Xcode, but it seems trace back to the GCC compiler (version 3.3).
I tried this with "gcc -g ctl.m". The only problem I see is that '_main' and some .objc cruft is undefined. Am I missing something?

Thanks for your prompt response, Justin. You're not getting the same result I got, although it appears that you did the same thing! (Were you using version 3.3, build 1495 of gcc?)

Here's exactly what I did in a Terminal window to get the results I reported in my original post:

[LEBsMacG4Cube:~] larry% mkdir GCCbugTEMP
[LEBsMacG4Cube:~] larry% cd GCCbugTEMP/
[LEBsMacG4Cube:~/GCCbugTEMP] larry% cat > ctl.h
//  -------- Contents of header file ctl.h --------
#import <Cocoa/Cocoa.h>
@interface Ctl : NSObject
{
    IBOutlet NSTextField *a;
    IBOutlet NSQuickDrawView *q;
    IBOutlet NSTextField *xPosText;     // Fails
//  IBOutlet NSTextField *xPosTex;      // Succeeds
}
- (IBAction)ctlMethod:(id)sender;
@end
[LEBsMacG4Cube:~/GCCbugTEMP] larry% cat > ctl.m
//  -------- Contents of source file ctl.m --------
#import "ctl.h"
@implementation Ctl
- (IBAction)ctlMethod:(id)sender
{
}
@end
