$NetBSD: patch-ac,v 1.1 2015/09/02 10:54:29 szptvlfn Exp $

First chunk:
Don't use _POSIX_C_SOURCE on SunOS with c99.

Next chunks:
Use a compile test, not a run test, for whether various rlimit values
are equivalent.  A compile test is sufficient because zsh uses these
values in switch cases, so they must be compile-time, if not
preprocessor-time, constants.

Last-but-one chunk:
Make this package build on Interix.  Patches provided by Hiramatsu
Yoshifumi in PR pkg/25946.

Last chunk:
Use -shared instead of -G on SunOS.
Fixes 64-bit package.
