Remove plperl isnan hack

petere · petere · commit b04ebca6cd84 · 2018-04-30T14:34:05.000-04:00
The code previously undefined isnan because of a compiler warning on
MinGW.  Since we now need to use isnan, we can't do that anymore.

We might need a different solution if the compiler warning is too
annoying.
