The function "internal_dfa_exec" in "pcre_dfa_exec.c"
has many calls to the function "_pcre_ucp_findprop"
that are wrapped within "#ifdef SUPPORT_UCP" blocks,
but has at least five instances that are not wrapped in
these same #ifdef blocks.

That is untidy, but would cause no harm, as the code could never be obeyed. I have tidied it up for the next release. (Comment by PH)
