I believe this is in reference to the following quote: http://pubs.opengroup.org/onlinepubs/9699919799/functions/V2...

The relevant quote is:

    other than errno with static storage duration other than by assigning
    a value to an object declared as volatile sig_atomic_t, or if the
    signal handler calls any function defined in this standard other than
    one of the functions listed in the following table.
