Forward: [ruby-dev:27237] Re: yaml warnig in verbose mode

Hi,

It is reported YAML emits a lot of warnings in VERBOSE mode.

Though I'm not sure why PrivateType and DomainType are
separated into syck/rubyext.c and yaml/types.rb, this patch
supresses the warnings.

And I strongly recommend to always add file names and line
numbers to eval.
