commit d669c129619ad3952fcabb263e307e3d48b12969
Author: Raymond Toy <toy.raymond at gmail.com>
Date:   Sun Dec 8 09:26:24 2013 -0800

    Update for ppc/darwin 10.5 and gcc 4.8.
    
    o Remove -no-cpp-precomp, which isn't recognized by gcc 4.8.
    o Add -static-libgcc so lisp doesn't need to have a compatible version
      of libgcc on the target system.
    o e_rem_pio2.c doesn't have aliasing issues, so remove the compiler
      flags.
