OK, so you're building it within the main Pg build system. Pg was successfully compiled, including files that use elog.h . Yet your extension doesn't compile, complaining about a macro/typedef conflict.
This makes me wonder: what's different?
Can you post the full sources of your extension, including the Makefile?

Here's the trimmed down version of the source and the Makefile (copied and modified from the 'cube' contrib project)
(with which I see the error related to redefinition)

PGDLLEXPORT Datum total_seconds(PG_FUNCTION_ARGS) {

}
