/*-------------------------------------------------------------------------
 *
 * 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!
