OpenSSL has some multiple-precision math support, as do various BSD- 
and MIT-licensed libraries.

No shortage of tooling, some of which has compatible licensing.  But 
you've undoubtedly seen all this.

Some folks are going to want IEEE quad and __float128, but how many and 
how soon?  Donno.  Extended-precision support has long been a hole on 
OpenVMS, excludiing the admittedly ugly approach of string math.
