Details

Related to #45629 about fc_vsnprintf() return value.

Change the "working vsnprintf()" configure check not to consider C89 return value (-1) in case of truncated output acceptable, but require C99 return value (what the lenght would have been if there was no truncation)

Comentario

Actually we can do this to all branches, including even S2_6. It's not dropping support for any systems, but just causing them to use fallback vsnprintf() implementation, that should work correctly (it doesn't at the moment, but #45629 is about fixing that)
