I thought it was only necessary to define UNICODE. _UNICODE seems like it
ought to be a compiler-internals sort of thing. (ANSI reserves all
identifiers beginning with _ for the compiler/library's internal use)

I notice you're using gcc to both compile and link your C++ file. Does
using g++ instead of gcc for both stages help any?
