  Gnulib module: sigprocmask
  
  Portability problems fixed by Gnulib:
  @itemize
  @item
  This function is missing on some platforms:
  mingw, MSVC 14.
  @end itemize
  
  Portability problems not fixed by Gnulib:
  @itemize
  @item
  In case of failure, the return value is wrong on some platforms:
  NetBSD 9.0 when libpthread is in use.
  @end itemize
  
  Note: Although @code{sigprocmask} officially has undefined behaviour in
  multi-threaded programs, in practice it is essentially equivalent to
  @code{pthread_sigmask}, with only a difference regarding the error
  return convention.  It's simpler to use @code{sigprocmask}, since it does
  not require linking with @code{-lpthread} on some platforms:
  glibc, NetBSD, OpenBSD, AIX, IRIX.
