Subject: [PATCH] Clean up buildfarm failures arising from the seemingly
 straightforward page macros patch :-(.  Results from both baiji and mastodon
 imply that MSVC fails to perceive offsetof(PageHeaderData, pd_linp[0]) as a
 constant expression in some contexts where offsetof(PageHeaderData, pd_linp)
 works fine.  Sloth, thy name is Micro.
