It sounds like the ISAM library was compiled on a pre-3.5 Development Set.
If so, the symbol names got truncated to seven or eight characters,
but your 3.5 compiler is not truncating the names (so called flexnames).
Thus any long name you call in your code will not match the same name in
the old library, because only the first part of the name is in the library.

I think the 3.5 ld command has a -T option to truncate the names, giving
you backward compatibility with old libraries.
