Minor compilation fixes

[lelandyang]

I have to say there still some bugs while trying to compile the windows port: I made it after little modification, I write it here for reference so that other users might benefit from the issue. Visual studio does not support C99 standard and inttype.h is not included, one can obtain a copy from http://code.google.com/p/msinttypes/ extract the zip ball and edit bchunk.c : #include <inttypes.h> to #include "./inttypes.h" then run the bat file to build.make sure %VS90COMNTOOLS%is in your system path!
