4  * Included from config.h to deal with replacing [v]snprintf() on older
5  * systems.  The #undef lines below cannot be directly in config.h as
6  * config.status modifies each #undef in config.h.in to either be a
7  * commented-out #undef or a functional #define.  Here they are used
8  * to avoid redefinition warnings on systems such as macos ca. 2024
9  * where system headers define [v]snprintf as preprocessor macros.
10  *
11  * Do not include this file directly, leave it to config.h.
