It seem to me that there is some steps not needed !

  $(LD) --base-file BASEFILE --dll -o DLLNAME OBJS LIBS -e ENTRY

  $(DLLTOOL) --dllname DLLNAME --def DEFFILE --base-file BASEFILE
        --output-exp EXPFILE --output-lib LIBFILE
 
  $(LD) EXPFILE -dll -o DLLNAME OBJS LIBS -e ENTRY

This make a relocatable DLL and the import library file (LIBFILE .a).
This has worked fine everytime for me.

For a non relocatable DLL you'll need (just from memory) :

  $(DLLTOOL) --dllname DLLNAME --def DEFFILE
        --output-exp EXPFILE --output-lib LIBFILE
 
  $(LD) EXPFILE -dll -o DLLNAME OBJS LIBS -e ENTRY

Pascal.
