[Bug middle-end/26374] Compile failure on long double

--- Comment #19 from beebe at math dot utah.edu ---
Thanks for the further comments on PowerPC, double double as fake long
double, and the news of gcc-12 on Fedora 36 for that CPU.  I'll soon
build a VM to get access to that combination.  I have VMs already for
PowerPC on CentOS 7 (big endian), CentOS 8 (little endian), and Debian
10 (little endian).

Let's consider the initializer bug an "unfixed (mis)feature" of gcc
history, and move on to better arithmetic!
