Subject: ruby 1.9.1 mingw32 under Windows

I've tried using ruby 1.9.1 compiled with mingw32 and had the following
error:

f = File.open('C:/1.tst', 'w') => #<File:C:/1.tst>
f.truncate(0) => 0
f.truncate(10)
Errno::EINVAL: Invalid argument - C:/1.tst
        from (irb):4:in `truncate'
        from (irb):4
        from
D:/Tuzhilin/ruby/ruby-1.9.1-p129-i386-mingw32/bin/irb.bat:20:in `<main>'

This code works perfectly on win32 version or 1.8.6-mingw32,
1.8.7-mingw32. Furthermore, this:

File.truncate('C:/1.tst', 10) => 0

works perfect as well.

Tried different builds of 1.9.1 and different versions of mingw32 gcc
compiler, no use =/
