STAR-2.4.0d does not build on OS X about star

Hi Laurent,

I have pushed the fix into the master branch - could you please test it and let me know if it works. I will make a tag after that. Apparently your compiler on Mac has stricter rules for poitner arithmetic than gcc.

Cheers
Alex

Thanks.

On OS X, clang is the compiler behind g++.

The fix lets the build progress a little further, but it is still failing:

The work around was to force the use of gcc.

If gcc 4.9 was installed with homebrew (currently the default/latest), one can edit the Makefile from CC := g++ to CC := g++-4.9.

The build is completing with that change.
