Many thanks for the report.

That is the main reason we do not pack the standard tests with the Lua
distribution; several libc's out there (and, sometimes, compilers) do
not pass our tests...

(Not long ago we had a problem where pow(2,3) were not exactly 8. VS
cannot convert double to unsigned correctly. We already had problems
with 'strtod', where the implementation accepted "." as a valid number;
and so it goes...)
