Updating gcc will fix this issue: e.g., 
http://superuser.com/questions/517218/how-do-i-install-gcc-4-7-2-on-os-x-10-8. 
(You'll probably have other issues after that, though. I still can't get this 
to work on OS X.)

Got it to work with the following steps:

1) Update gcc to 4.7: 
http://superuser.com/questions/517218/how-do-i-install-gcc-4-7-2-on-os-x-10-8
2) Change "-march=native" to "-msse4.2" in makefile
3) Add "-I/usr/include/sys" to makefile "CFLAGS = " statement

It compiles if you remove the -Ofast, -Wno-unused-result and -march gcc 
options, and replace malloc.h with stdlib.h in the include statements. There 
might be a better way, though.

Thanks eaton...@gmail.com - that appears to have worked (binaries run, at least 
when not provided with arguments).
