Hello, I was unable to get DBD::Sybase 1.09 to compile against Syb 15.5.5 on Windows XP, with MSVC 2008 Epxress; it was borking on the /LC:\Sybase/OCS-15_0/lib bit. After messing around with Makefile.PL and the Makefile, I eventually stumbled on adding this to the LDLOADLIBS = line:

"C:\Sybase\OCS-15_0\lib\libsybct.lib" "C:\Sybase\OCS-15_0\lib\libsybbl
+k.lib" "C:\Sybase\OCS-15_0\lib\libsybcs.lib" "C:\Sybase\OCS-15_0\lib\
+libsybdb.lib"

Obviously, that should be changed for your install directory if necessary. I don't know whether this is a known MakeMaker/MSVC problem, but hopefully this might be helpful to anyone else whose employer makes them use Windows.
