strto**d**128 ... name collision with 'strtod128' for decimal128 types from
libdfp?? can't even say if that or something from glibc is called on my system. 
It works, but I'd like to understand, to be able to tell to others.  
Can anyone shed some light how to distinguish, where to find and how to
activate strtof128?  :-)  merry X-mas
