Fixes to enable FreeBSD support

[gmazzola]

Hello Brandyn,

I am using a FreeBSD-based Hadoop cluster for a project, and Hadoopy seems like an excellent way to manage Hadoop through Python. However, I discovered a few Cython compilation errors when I built the Hadoopy package on FreeBSD.

After an hour of debugging, I discovered the root cause of the problem. Your code calls the fgetc(FILE *) function, but passes a void * pointer instead of a FILE * pointer. On most platforms this behaves as expected, but FreeBSD defines FILE as a structure instead of a standard integer. The FreeBSD fgetc implementation references members of this struct, which caused compilation errors.

In this pull request I changed void * to FILE *, which fixes the problem while maintaining compatibility with all platforms.

Thanks!

Gregory

I confirm that there is such a problem. I would also like to notice that in FreeBSD glibc doesn't support --version flag.
