Subject: [PATCH] src: more tolerant snprintf() local override (#881)

`#undef snprintf` before redefining it, when `HAVE_SNPRINTF` is not
defined, even though `snprintf` is available and it should have been.
Possibly with 3rd party builds.

Downside is that cases of missing `HAVE_SNPRINTF` are less trivially
detected at compile-time.
