cannot open file 'LIBC.lib'

I changed a workspace developed in VC 6.0 to VS 2008. When I tried to build the workspace I am getting the following error message. How can I correct the problem?

fatal error LNK1104: cannot open file 'LIBC.lib'

I am getting the following messages when I ignored libc.lib
