Tree view 
<server/c.h> (a file that gets included in a user's server extension
compilation) contains the line

  # if _MSC_VER > 1400

In the compiler is not Microsoft C at all, _MSC_VER is undefined, and in some
environments, the reference to it is an error (e.g. Gcc with -Wundef -Werror).

So that this header file can work in all environments, it should have an
#ifdef.

I see this in Postgres 8.4.3.
