Thanks a lot for the hint. I rebuilt latest msys2-runtime, but
hostname.exe still fail on long name, reported "Operation not
permitted" as before.

Now I'm wondering if there is anything related to newlib VS winsup:
there are two gethostname implementations, one is in
newlib/libc/sys/linux/gethostname.c, the other is in
winsup/cygwin/net.cc,
is it possible that Cygwin is using the newlib version but MSYS2 is
using the winsup version?

Thanks a lot!
