I have a 'kitchen sink' Cygwin installation from 2013-01-14. This gives 
'rebase' errors when running the following command (taken from a 
./configure script):

$ ruby -r mkmf -e 'exit(have_func("rb_hash_foreach") ? 0 : 1)'
checking for rb_hash_foreach()...       0 [main] ruby 3064

The 'rubyrebase' shell script (submitted to this list about a year ago) 
came to my rescue:
http://www.cygwin.com/ml/cygwin/2012-02/msg00701.html

Please could you consider adding this utility to our ruby package, in a 
similar way to the 'perlrebase' script in Cygwin's perl. Further, would 
it be possible to run 'perlrebase' and 'rubyrebase' during setup's post 
install? The _autorebase package does a great job with executables, but 
I understand that it doesn't work with ruby gems or perl modules.

Many thanks in advance for considering this.

Dave.
