Hi Kevin,

A Google search of "error LNK2001: unresolved external symbol __ftol2" indicates 
that:
If your source code includes a cast from double to long types, VC7 will generate 
a call to _ftol2.

Indeed, build_taucs_win32_for_CGAL.bat expects to be called from a Visual C++ 
7.1 prompt shell (see CGAL-README.TXT).
Which version of VC++ are you using?

Best regards,
