patch 9.1.0274: MS-Windows: a few compiler warnings

Problem:  MS-Windows: a few compiler warnings
Solution: Change variable types to resolve compiler warnings
          (Mike Williams)

Windows compiles were reporting a few size_t to signed integer
conversion warnings that can be resolved by changing the variable
declarations to be size_t to start with.
