So here is a recap.  The first one has meson.build change from
Patrick squashed in, the second "errno" based one was what made
me write the last one, and is kept as-is.  The third one introduces
NOT_A_CONST() marking to an expression to tell the compiler not to
be overly aggressive to optimize it out.

Jeff King (2):
  config.mak.dev: enable -Wunreachable-code
  run-command: use errno to check for sigfillset() error

Junio C Hamano (1):
  git-compat-util: add NOT_A_CONST macro and use it in atfork_prepare()
