3  * header.h
4  * Replacement header file for Snowball stemmer modules
5  *
6  * The Snowball stemmer modules do #include "header.h", and think they
7  * are including snowball/libstemmer/header.h. We adjust the CPPFLAGS
8  * so that this file is found instead, and thereby we can modify the
9  * headers they see. The main point here is to ensure that pg_config.h
10  * is included before any system headers such as <stdio.h>; without that,
11  * we have portability issues on some platforms due to variation in
12  * largefile options across different modules in the backend.
13  *
14  * NOTE: this file should not be included into any non-snowball sources!
