See and scan
for "How to make DLLs using EGCS". I've just updated my dllhelpers
package to version 0.2.5 that provides examples for C, C++ and F77
DLLs (sorry, not ObjC yet).

Be warned however that the design of MS DLLs makes it extremely hard
to create DLLs from C++ code in some cases (especially when you're 
using exceptions, RTTI and a few other recent C++ features in a DLL). 
For most "normal" code, it should work just fine. Cygwin runtime itself
is a C++ DLL.
