The issue is that LD _does_ take DEF files as input - but not in the way you
seem to assume.
When you link a DLL (or EXE for that matter) and pass it a DEF file at the same
time, the DEF file overrides what symbols to export, instead of the regular
logic (functions marked dllexport, or exporting everything modulo explicit
ignores, etc). See the section in the manual:
