Don't implement os.unsetenv() in C using SetEnvironmentVariableW(name, NULL) anymore, but implement it in Python as os.putenv(name, ""). _wputenv() is preferred since it updates the CRT, whereas SetEnvironmentVariableW(name, NULL) does not. Replace also lambda functions with regular functions to get named functions, to ease debug.

There was a problem hiding this comment.
This looks too complicated and obscure. Many lines are duplicated with small differences. Would not it be easier to implement nt.unsetenv() on C?
