    Check if DEBUG is defined in regex_internal.c
    
    The DEBUG macro is checked for its value in one place and if it is
    defined in another.  Make this consistent across the two cases and use
    the same style that we did in mktime.c, which is to check if the macro
    is defined and it is set.
