Hi,

On OS X 10.9.x, gcc points to clang. I installed gcc-4.9.0 from source
(follow instructions on this page, for example:
<http://solarianprogrammer.com/2013/06/11/compiling-gcc-mac-os-x/> to
get a working gcc. I don't use a package manager on OSX these days, I
compile/install what I need, from source.)

I then edited mkfiles/mkfile-MacOSX-386 to point to the newly built
gcc (I called the gcc binary gcc-4.9.0). Here is the complete file.
