Propably you mean coff2omf :) ! Anyway ! In an ideal world of a common ABI(Application Binary Interface) between (compiler and linker) vendors you could use the vc compiled dll's with borland.Unfortunatelly this is not the case and every opencascade package needs compilation with bcc ! Anyway ... enough with theory ...
You can download OCC package for Borland from :
http://62.1.3.26/download/OCC_63_Borland.7z
I hope the above will help !
Godd luck with your effort
