No. I've compiled test program without any optimizationf flags.
Just -m64, which tells compiler to generate 64-bit code.
(in 32-bit mode there is no __int128, so problem wouldn't manifest
inself).

From the other side, when I've tried to resolve issue with not worked
test, I've copied all gcc flags from config.log, and test program
returned 1 with exactly same flags.

Probably, I should have to regenerate configure with autoconf. instead
of applying patch to configure.
