Won't compile with VC++7.1

[Noboru Uchida]

Excuse my poor English.
Under Windows MSVC7.1, I needed some modification to build.

1) RIPEMD160.c and _counter.h includes stdint.h, which VC++7.1 doesn't have.
    I needed to copy cygwin gcc's stdint.h into src/ and slightly modify it.

2) In _counter.h, semicolon apears after the macro PyObject_HEAD, which causes compile error.

3) Some functions declared as "inline", which VC++ doesn't support for C sources.
   Instead, VC++ has Microsoft specific extension "__inline" for C.
   Using #ifdef _MSC_VER or something would be better.
