On Windows, vim uses C runtime library(probably msvcrt.dll). And it store the environment varibles in memory of process. It is passed to external processes at the time of starting it. So dll can't get them via getenv. To solve this problem, one of way is add code calling SetEnvironmentVariales/putenv both into vim. Another way is add code calling GetDOSEnvironment instead of getenv into your dll. I'm not sure the second way.
