This one is about 3 failures I have in "test_win32ole_variant.rb".
Those are:

test_s_array
test_conversion_str2num
test_conversion_ole_variant2ole_variant

After looking at the win32ole.c, I see that the default locale
is LOCALE_SYSTEM_DEFAULT. That means that the locale
is from the Windows, and is not affected by the console settings.

Since I am using "Serbian Latin", which sets coma as decimal
separator (eg. 123456,78), all three tests fail simply because
Windows API tires to convert string to number using wrong locale.
String is in US locale, but conversion API uses system default.

Since WIN32OLE.locale= exists, setting it to 1033 (US English),
solves all three tests as "pass". It looks like this:

def test_conversion_str2num
WIN32OLE.locale = 1033 # set US-Eng locale - number with decimal point
obj = WIN32OLE_VARIANT.new("12.345", WIN32OLE::VARIANT::VT_R8)
assert_equal(12.345, obj.value)
end

I've created the following patch based on above analysis.
It seems to work fine.
