Further empirical tests turned out that the environment in Windows NT
is not limited, at least not up to a tested size of about 800K.

But there is a big problem in Windows nevertheless.  When using ASCII
functions to access the environment, as Cygwin does, the environment
is silently cut off at 32K.  There's no error message or any hint
in the documentation that something like this would happen when trying
to retrieve the environment.  Trying to start another process with
an ASCII environment > 32K results in an error code returned by
CreateProcess.  So, for now you have to live with an environment < 32K.
