mst06/cmake/modules/SetWindowsEntrypoint.cmake
David Korth 30bad7d0d6 Added Unicode support for the Windows build.
- tcharx.h: Copied over from RVT-H Tool.
- SetWindowsEntrypoint.cmake: Likewise.
- CMakeLists.txt: Compile with -DUNICODE and -D_UNICODE, plus several
  other useful things like MSVCRT secure overloads.

TODO:
- Enable wildcard expansion for mst06?
- Move Windows compiler settings to a separate .cmake file.
