rb_w32_getenv has naive implementation
In change set 10650 (and according to discussion in ruby-talk:205123), the rb_w32_getenv implementation was changed. However, I believe that the correct approach according to windows documentation should be to call GetEnvironmentVariable and check GetLastError. If the variable exists, then S_OK is returned or some error code in other case. Call to GetEnvironmentStrings and home made enumeration is cumbersome.

There is a patch to use GetEnvironmentVariable() instead of using GetEnvironmentStrings(), written by Nobu.
However, this patch is as you see complex at the same level of current code.
Nobu and I discussed about this issue, and reached to a conclusion that we maintain the status quo for the time being.
