def file that produces a syntax error

The attached file produces a dlltool syntax error:
$ dlltool -l libusbx.a -v --def libusb-1.0.def
dlltool: Processing def file: libusb-1.0.def
dlltool: Syntax error in def file libusb-1.0.def:0
dlltool: Processed def file
dlltool: Processing definitions
dlltool: Processed definitions
dlltool: Creating library file: libusbx.a
dlltool: run: as   -o dmuhh.o dmuhh.s
dlltool: run: as   -o dmuht.o dmuht.s
dlltool: Created lib file

The resulting lib file is missing exports and therefore leads to undefined references when using it.

This is with dlltool 2.22.52.20120429

Other versions of dlltool:
2.21.53-20110731
2.22 (release)

do not have this behavior and work fine.
