ActiveRecord on cygwin with sqlite3

[alexy.khrabrov]

I've successfully installed sqlite3-ruby on cygwin (can run a simple
database fetch), but the activerecord test suite fails. I'm running it
as described in the RUNNING_UNIT_TESTS doc:

$ ~/gems/activerecord-1.13.1
$ rake test_sqlite3
(in /usr/lib/ruby/gems/1.8/gems/activerecord-1.13.1)
/usr/bin/ruby -Ilib:test:test/connections/native_sqlite3
"/usr/lib/ruby/gems/1.8
/gems/rake-0.6.2/lib/rake/rake_test_loader.rb"
"test/aaa_create_tables_test.rb"
"test/adapter_test.rb" ... "test/transactions_test.rb"
"test/unconnected_test.rb" "test/validations_test.rb"

../test/../lib/active_record/base.rb:244: undefined method
`cattr_accessor' for ActiveRecord::Base:Class (NoMethodError)

rake aborted!
Command failed with status (1): [/usr/bin/ruby

I also noticed that among the targets, there is build/drop tables for
mysql/postgresql, but not sqlite. Can it be related to the above
problem?

Cheers,
