The NS variant produces the failure when compiling with -fast. With - 
Os and less the build is OK. When I configure --with-wide-int the  
failure becomes:

        Loading window...
        Loading files...
        Loading cus-face...
        Loading faces...
        Loading button...
        Loading startup...
        Loading .../emacs-24.1.50/lisp/loaddefs.el (source)...

If I spend some time I can manually make Apple's GCC 4.2.1 to compile  
as with -fast, because all the switches are documented (-O3 plus many  
extras plus optimisation for the 64-bit G5 processor/IBM PowerPC 970  
variants compensated by -mcpu=7450 -mtune=G4) and find out which  
switch causes the defect...
