Sorry for the late reply.
I got it. I'll revert and apply Joerg's patch. thanks.
BTW, I have a question. uint64 is defined as unsigned long long on NetBSD/aarch64.
but on other OS (Linux,FreeBSD), it seems that uint64 is defined as unsigned long.
(grep 'AARCH64.*INT64_TYPE' /usr/src/external/bsd/llvm/dist/clang/test/Preprocessor/init.c)
Linux long
FreeBSD long
NetBSD long long
OpenBSD long long
DARWIN long long
Which type should be better?
