* 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 !
