I believe the bug is triggered by the fairly unusual event you have a '.'
in the package name, and the change in 2.2.1 to 2.2.1 patched was to add
> LIBRARY R.native.dll
(which is what my workaround in ld.exe was doing another way).
Since we are told that is the correct form and we were using it
incorrectly before, I don't really know how to work around this. For you,
just delete .dll in the following line in src/gnuwin32/MkRules
@$(ECHO) LIBRARY $*.dll > $*.def
but that is not a general solution.

Hmm, only 3.4.5 is there as a candidate.
