The following causes a compile warning on recent pcre2 versions:

6. The prototype for pcre2_substring_list_free() specified its argument as
PCRE2_SPTR * which is a const data type, whereas the yield from
pcre2_substring_list() is not const. This caused compiler warnings. I have
changed the argument of pcre2_substring_list_free() to be PCRE2_UCHAR ** to
remove this anomaly. This might cause new warnings in existing code where a
cast has been used to avoid previous ones.
