Ok, fine.

-O..first level optimize code, but Octave.app internally uses -O3 optimization 
by default. So you can just forget about -O. The option -o normally followed by 
a <name> means give the compiler object output the name <name>. -O and -o are 
not the same but different.

The parameter "-Wp,-DMX_API_VER=0x07030001" means: -Wp..tell the preprocessor 
-D..define MX_API_VER to a value 0x07030001. If you have a look at any of the C 
files from libsvm, there it says

  #if MX_API_VER < 0x07030000
  typedef int mwIndex;
  #endif

but your reported error was

  svm_model_matlab.c:8: error: redefinition of typedef 'mwIndex'
  .../octave/mxarray.h:89:
  error: previous declaration of 'mwIndex' was here

Finally I replaced all *.obj names to *.o because the default on Mac systems is 
.o (.obj is Windows specific). Hope this answers your questions.
