wxSetEnv-wxExpandEnvVars inconsistent in Windows

Patch: no


In Windows, the wxSetEnv() code uses the
SetEnvironmentVariable() Win32 API to update the
process' environment, yet the wxExpandEnvVars() uses
the _environ block to do the expansion.

The two are not compatible - it should either use
_putenv() and the existing wxExpandEnvVars() code or it
should use SetEnvironmentVariable() and

I, personally, would prefer the former because it would
allow the use of the ${var} format in Windows.

The workaround of calling _putenv() explicitly within a
defined(_WIN32) macro block works for now.

Fixed by revision 42471, which should have ensured that it's correct in 2.8.0 and later.
