+Subject: msvcrt: Fix passing of explicit environment to spawn/exec calls
+
+Explicit sets of environment variables passed to spawn/exec are
+consistently converted to wide character environment blocks.  Because
+CREATE_UNICODE_ENVIRONMENT isn't included in the process creation flags
+the environment block is incorrectly passed through another conversion
+to wide characters in create_process_impl.
