[Comment] reader.c is newly edited file. Error happens with exact file. I think it should be fixed!!

I cloned current git head, and then I confirmed that the error occur. Next, based on your suggestion, I downloaded "portable_endian.h" and edit the file "reader.c" to include "portable_endian.h". This time, make was succeeded. So my issue might be solved.
