Use gcc to link. libc, libsocket and libnsl are all included in
libcygwin which you don't need to propagate to the linker:

gcc -shared -o libbridge.dll \
    -Wl,--out-implib=libbridge.dll.a \
    -Wl,--export-all-symbols \
    -Wl,--enable-auto-import \
    -Wl,--whole-archive \
    bridge.o nwutil.o jagsocket.o \
    -Wl,--no-whole-archive \
    ${dependency_libs}

where ${dependency_libs} may be any libraries your library is
depending on (like -lstdc++ for C++ libraries).

-Wl,--out-implib=libbridge.dll.a results in the import library which
you can use to link your application against (with -L/path -lbridge).
