Re: infos on compiler flag

Hi Alex

I think you are using the FSF build of the compiler rather than the Apple 
one.

AFAIK this is a very unsupported combination.   It is also sub-optimal 
because it omits a substantial number of important optimisations which 
have been added by Apple but not yet accepted by the FSF people.  The 
speed difference has been reported as around 40%!

Do you have some compelling reason not to use Apple's standard compiler 
(accept for the one function call patch)?  This version is well tested. 
Indeed it almost certainly much the best tested of any of the gcc 
objective-C compiler versions, because it is actually used to build the 
operating system.
