Are you sure that the current linker does not work ? When I tried it, using the test case you supplied, but without the patch applied, I got this: % make ../gcc/g++ -B ../gcc/ -g -save-temps -c -o dll.o dll.cc ../gcc/g++ -B ../gcc/ -g --shared -L ../i686-pc-cygwin/newlib -L ../i686-pc-cygwin/libstdc++-v3/src/.libs dll.o -o dll.dll ../gcc/g++ -B ../gcc/ -g -save-temps -c -o client.o client.cc ../gcc/g++ -B ../gcc/ -g -o client client.o -L ../i686-pc-cygwin/newlib -L ../i686-pc-cygwin/libstdc++-v3/src/.libs -L. -ldll Info: resolving _var by linking to __imp__var (auto-import) Info: resolving test::var by linking to __imp___ZN4test3varE (auto-import) Cheers Nick -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
