Confirmed:

    $ grep -A3 AX_GRE /usr/include/regex.h
    #define RE_SYNTAX_GREP                                                  \
      (RE_BK_PLUS_QM              | RE_CHAR_CLASSES                         \
       | RE_HAT_LISTS_NOT_NEWLINE | RE_INTERVALS                            \
       | RE_NEWLINE_ALT)

ACK.
