                                     malloc() is used by the POSIX API
         PCRE_CONFIG_STACKRECURSE  Recursion implementation (1=stack 0=heap)
         PCRE_CONFIG_UTF8          Availability of UTF-8 support (1=yes 0=no)
         PCRE_CONFIG_UNICODE_PROPERTIES
                                   Availability of Unicode property support
