   1 /*
   2  * Here we postprocess autoconf generated prefix-config.h entries.
   3  * This is generally for things like "off_t" which is left undefined
   4  * in plain config.h if the host system does already have it but we do
   5  * need the prefix variant - so we add here a #define _zzip_off_t off_t
   6  *
   7  * This file is supposed to only carry '#define's.
   8  * See <zzip/types.h> for definitions that might be seen by the compiler.
