I've downloaded and installed the current cygwin version of Ruby/ODBC
(0.94?) on Ruby 1.6.3, Win2K sp2.  When I try to open a MS SQL Server db, I
get a seg fault:

C:\fljava\ruby\ConvertGeo.rb:6: [BUG] Segmentation fault
ruby 1.6.3 (2001-03-19) [i386-cygwin]
      0 [sig] ruby 1648 stackdump: Dumping stack trace to ruby.exe.stackdump

I will now give Ruby 1.6.4 a try.
