* 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!
