Sam:

That is not what my proposal said.  My proposal said that a macro would
be used to replace the existing calls to getenv() with win32_getenv()
on Windows systems.  The same for setenv() and win32_setenv().

The only change for POSIX systems is that there would need to be a macro
that is a no-op added so that it can be used to free the allocation
from win32_getenv() on Windows.
