SQL Anywhere ODBC 32 bit problem

Dredged up my old Sql Anywhere 5.05 version to test some ODBC code.
Compiles and runs fine on 16 bit but provides a warning about no support
for “small” 32 bit version when I try and do the connect with the 32 bit
version. Why bother providing the 3r version of the libraryif it doesn’t
work. Anyone know of a solution to this one.
