Multiple Definition of "_Unwind_Resume"

I'm using mingw gcc 4.4.0 w/ dw2 exception handling on a windows xp machine. I'm using the latest source (I think - v2.8.3). When compiling, I get a multiple definition error for "_Unwind_Resume." The shared libraries (dlls) compile fine, but it errors out when attempting to link a test C++ program. I didn't used to get any errors like this, but I was using a slightly older version of gcc and it was using SJLJ exception handling. Here's the output:
libtool: link: g++ -g -O2 -Wl,--exclude-libs=libintl.a -o .libs/ex-cxx.exe ex-cxx.o ./.libs/libexamples.a ../../lib/.libs/libgnutls.dll.a ../../libextra/.libs/libgnutls-extra.dll.a ../../gl/.libs/libgnu.a ../../lib/.libs/libgnutlsxx.dll.a /C/Build/Windows/Win32/Release/obj/gnutls/lib/.libs/libgnutls.dll.a -lz /C/Build/Windows/Win32/Release/lib/libgcrypt.dll.a /C/Build/Windows/Win32/Release/lib/libgpg-error.dll.a -lws2_32 -L/C/Build/Windows/Win32/Release/obj/gnutls/lib/.libs -L/C/Build/Windows/Win32/Release/obj/gnutls/libextra/.libs -L/C/Build/Windows/Win32/Release/lib -L/C/Build/Windows/Win32/Release/libc

If there's a way to avoid compiling and running this particular test, that wouldn't be ideal, but it would be "okay" enough for now.
I appreciate any help anyone can offer.
