  Yep, confirmed.

  It appears to lack a couple of supporting DLLs:

$ cygcheck /usr/lib/perl5/vendor_perl/5.10/i686-cygwin/auto/Win32/ODBC/ODBC.dll
F:\cygwin-1.7\lib\perl5\vendor_perl\5.10\i686-cygwin\auto\Win32\ODBC\ODBC.dll
  C:\WINNT\system32\KERNEL32.dll
    C:\WINNT\system32\NTDLL.DLL
  F:\cygwin-1.7\bin\cygwin1.dll
    C:\WINNT\system32\ADVAPI32.DLL
      C:\WINNT\system32\RPCRT4.DLL
cygcheck: track_down: could not find cygiodbc-2.dll

cygcheck: track_down: could not find cygiodbcinst-2.dll

  F:\cygwin-1.7\bin\cygperl5_10.dll
    F:\cygwin-1.7\bin\cygcrypt-0.dll


  According to the package search, these don't exist anywhere in the distro.
I found an announcement posting for perl-libwin32 that says

"To build from source you will need the libiodbc package, and apply a
small patch:"

http://www.cygwin.com/ml/cygwin-announce/2008-06/msg00022.html

so with a bit of luck you should be able to build yourself a copy quite easily.

    cheers,
