That's a bummer but not a real problem for you.
You can always check for the version using a regular
expression that will treat the contents of $] as a string.
And strings don't care about floating point arithmetics.

If the only place you had 'use warnings' was somewhere in
the beginning of your script than using -w in your sh-bang
is going to have the same result. So in that case, it can be
the best solution.
