MSVC: Fix some compiler warnings In particular, using the normal (or production) compiler warning level (-W3), msvc complains as follows: .../sha1.c(244) : warning C4018: '<' : signed/unsigned mismatch .../sha1.c(270) : warning C4244: 'function' : conversion from \ 'unsigned __int64' to 'unsigned long', possible loss of data .../sha1.c(271) : warning C4244: 'function' : conversion from \ 'unsigned __int64' to 'unsigned long', possible loss of data Note that gcc issues a similar complaint about line 244 when compiling with -Wextra.
