I'm not sure what name mangling has to do with this, but actually, there is another reason to search the .a file before the .dll file. libcygwin.a contains references to things in cygwin1.dll *and* it contains "static" references. If you link cygwin1.dll first you will get unresolved symbols. So, you can't do things this way. cgf
