Gcc had a multiple precision package for that purpose. It was simple and
efficient and never gave any problems, all features that made it obsolete.

Why make it simple when you can make it very complicated?

They now use GMP, a HUGE package that can multiply numbers of ANY
size, up to thousands of digits precision, complete with assembler
code tailored for each processor, with obscure macros, with  thousands
of complications that aren't at all needed for a compiler.

That is progress my friend. PROGRESS means:

If it is simple, it is wrong.
