The data type of "index_substr_any_len" and "index_substr_any_step" are unsigned
int. They should share the same flag ARG_UINT as "index_substr_if_{min,max}len"

/* servers/slapd/schema_init.c */
158 unsigned int index_substr_if_minlen = SLAP_INDEX_SUBSTR_IF_MINLEN_DEFAULT;
159 unsigned int index_substr_if_maxlen = SLAP_INDEX_SUBSTR_IF_MAXLEN_DEFAULT;
160 unsigned int index_substr_any_len = SLAP_INDEX_SUBSTR_ANY_LEN_DEFAULT; 
161 unsigned int index_substr_any_step = SLAP_INDEX_SUBSTR_ANY_STEP_DEFAULT;

In the current code, they are "ARG_INT" which convert -1 to be 4294967295.
