164    In a Windows environment, if you want to statically link an application program
165    against a non-dll <b>pcre.a</b> file, you must define PCRE_STATIC before
166    including <b>pcre.h</b> or <b>pcrecpp.h</b>, because otherwise the
167    <b>pcre_malloc()</b> and <b>pcre_free()</b> exported functions will be declared
168    <b>__declspec(dllimport)</b>, with unwanted results.

661    This option changes the way PCRE processes \b, \d, \s, \w, and some of the
662    POSIX character classes. By default, only ASCII characters are recognized, but
663    if PCRE_UCP is set, Unicode properties are used instead to classify characters.
