The manual page clearly states that
gettid() is Linux-specific and should not be used in programs that are intended to be portable.
Unfortunately, it looks like macOS implemented the functionality and defined SYS_gettid accordingly, only to deprecate syscall() altogether with 10.12 (Sierra), released last late year.
To avoid compilation errors, call gettid() on Linux only.
