   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!
