Yes, that is not an issue, but the question is if the relatively small cost of adding a bit too jmp_buf makes it worth it, as long as people understand that there is no fp support in klibc.

We are (only just) upgrading from Samba 1.9.18p10 to the latest 2.2.7a. We run Eudora 5.1 on our PC clients, which pick up their mail boxes from home directories on Solaris machines using samba shares. When we install the new Samba, all our Samba clients slow down incredibly. I suspect here is a change in the Samba config file requirements between the versions? Has anyone else already solved

arm64 uses generic syscalls, and does not include the "noat", "noflags", and "deprecated" syscalls. i.e. __ARCH_WANT_SYSCALL_{NO_AT|NO_FLAGS|DEPRECATED} This patch adds the syscalls needed for klibc to run on arm64.
