While mingw would otherwise fall back to
__attribute__((visibility("default"))), that appears to only work as long as
no symbols are declared with __declspec(dllexport). But we can end up with
some, e.g. plpython's Py_Init.
It's quite possible we should do the same for cygwin, but I don't have a test
environment for that...
