The same freaking issue was been mentioned 10 years ago. No one actually tr=
ies
to fix this until I come.

There are a lot of historical issues with GCC implementations and I tried to
submit patches to fix them.

like BUFSIZ macro on windows, which is wrong for 30 years (just fixed in GC=
C11
because I reported the bug).
addcarry. (still does not work)

The freestanding C++ is an absolute joke. Not just because of the reason of
exception handling. The GCC team did a horrible job in the past.

Of course LLVM is even worse, but I am not going to trash talk about that h=
ere.=
