Hi all,

System is Windows XP Pro SP3, Ruby is installed from rubyinstaller-1.9-rc1:
C:\>ruby.exe -v
ruby 1.9.1p243 (2009-07-16 revision 24175) [i386-mingw32]

C:\>gem list --local ini

*** LOCAL GEMS ***

ini (0.1.1)

Calling irb -r ini returns following errors:

C:\>irb -r ini

It should be simply a syntax error in 'case' statement.
Following patch should fix the issue.

HTH. Thanks for the gem.
