annotate src/mail/ngx_mail_proxy_module.c @ 9266:93bbb9fbf30d default tip
Fixed compilation on NetBSD 10.
NetBSD 10 changed struct kevent's udata type from "intptr_t" to "void *",
similarly to how it is defined on other systems. This breaks compilation,
since intptr_t is assumed on NetBSD.
Fix is to limit special intptr_t handling to NetBSD versions before 10.0.
To simplify testing, relevant definitions are moved from configure to code
(which seems to be the right thing anyway).
