I think that the 64bit libs on windows should be called libsybct64.lib/libsybct64.dll - you need to have a 64 bit client installed (the default client is still 32 bit only IIRC).

Comment on Re^3: Installing DBD::Sybase using CPAN
Yep, Mike, you are correct, but I still couldn't get it to pass tests. I'm dropping back to 32 bits. I need to get this done ASAP and I don't need to address more than 4GB of memory in any process.
