--- Comment #10 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
If I replace the files /usr/include/objc/NSObject.h and
/System/Library/Frameworks/Foundation.framework/Headers/NSString.h with the
corresponding files from
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/
The errors reduce to

with -m64. The errors for are of the kind
objc[1436]: -[Forwarder display]: unrecognized selector sent to instance
0x7f9ce9d04f30 (no message forward handler is installed)
Is there a canonical way to force obj(c|-c++) to use the include files in
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/
instead of the native files in /usr and /System?
Note that some remaining errors will go away if the same is used for
/System/Library/Frameworks/Foundation.framework/Headers/NSArray.h.
