That's in this case because it's our own extern, that itself would probably be fixable, but: > So what we currently know is that on cygwin, some of the core system > include files have been declspec'd, but others haven't; and headers > for third-party libraries like libxml and libreadline mostly haven't. it's not going to work for the external libraries. > I'm starting to get the feeling that we're going to have to admit > defeat and not try to use --disable-auto-import on cygwin builds. > That platform is evidently not capable of supporting it.
