SDL/test/testautomation_stdlib.c
nmlgc 8824eace93 testautomation: Test SDL_snprintf() for doubles >LLONG_MAX and <ULLONG_MAX 
The uclibc version of SDL_snprintf() is currently limited to values
<ULLONG_MAX due to the `unsigned long long` cast in SDL_PrintFloat(),
but it makes sense to at least ensure that it does support the full
unsigned 64-bit range. This also covers the one defined case where a
32-bit MSVC build can't assume that _ftoul2_legacy() == _ftol2().
