You may find it simpler (and faster) to use the gcc driver instead of
dllwrap:

g++ -shared -o
libim.dll -Wl,--export-all -Wl,--output-def,im.def -Wl,--out-implib,libim.a
imsock.o [ ... more object files ... ] -lwsock32

You should not need to add c:/mingw/lib to the library search path.

Go to http://www.mingw.org/ and enter your search.
