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