That configure check tests whether snprintf produces the right result at
runtime. It doesn't check whether the compiler will generate a warning
about it. It looks to me like Pavel has a compiler that is out of sync
with his libc; which is a platform configuration mistake that he needs
to fix.
Another possibility is that configure chose to not use the system
snprintf at all, in which case %lld is the correct syntax to use but gcc
might well have some different expectation. Without seeing the
config.log results it's hard to be sure about that one; but in any case
it's hard to credit that there are any modern machines where snprintf
can't handle long long int, so this still suggests a platform problem.
