     Did you tell Turbo C to NOT prepend an underscore ("_") to a name?
Normally (i.e., the default action), the compiler prepends underscores to a
name and stores these modified names in the .OBJ file.  I can't remember
the exact details, but, in the integrated environment, there is a compiler
switch (and possibly also a linker switch) under the "Options" menu.  Make
sure that it (they?) are set correctly.
