Doesn't that depend on whether symbols are found in the DLL by symbol

It does, but do you have a choice? I couldn't find a way.
I think this as been discussed before, but here goes...
How the import lib was created decides if the exe will import symbols by
ordinal or by name. That would mean that since the A5 .def file
specifices the ordinals, and the linker uses the .def when creating the
import lib, ordinals are currently being used. But as long as NONAME
isn't specified in the .def, the DLL will still export the symbols both
by name and ordinal.
It should be ok to dump the def file and just use declspec(dllexport)
instead. According to [1], the penalty for importing by name is
negligible. A better reason for using ordinals would be to save space,
but Allegro doesn't export that many symbols. The symbol names currently
occupy about 50 kB in the DLL.
The Borland .def file renames the symbols, so I guess that has to stay
if bcc is still to be supported. Which I suppose it isn't.
