It could be caused by the fact that the linker only does a single pass on
any given library or object file, so if a symbol is referenced prior to the
library that contains the symbol has been processed, maybe the linker
decides that it's an error and not wait until in might be resolved by the
end of the linkage process.

By doing a full compile of DWT again, I think the linker is processing the
object files and the libraries so it catches the early reference.

Try placing the another reference to the library that contains the item,
earlier in the command line, so the library is actually used twice on the
command line.
