Yes, I tested with VC++ 9.
It fails as same as your test.
I guess "msvcrt" is valid for VC++ 6.
The situation became more complex since VC++ 8.

Refer to http://msdn2.microsoft.com/en-us/library/abx4dbyh(VS.80).aspx

You should modify the line

Umask = API.new('_umask', 'I', 'I', 'msvcrt')

to

Umask = API.new('_umask', 'I', 'I', 'msvcr80')

It requires Microsoft Visual C++ 2005 SP1 Redistributable Package (x86)
