[Dxspider-support] Argument " " isn't numeric

[Dirk Koopman]

It is 'modern' perl that seems to be tightening up on stuff we, aged, 
perl programmers have always taken for granted. It used to be a warning 
that was issued when it (might have) mattered, such as doing arithmetic 
on 'ABC'. But in this it is because the argument is undefined, it emits 
this warning. But I will fix it nonetheless.
