-/** string pcre_fix_posix_classes (string $regexp)
-*
-* Older version (pre 3.x?) of the PCRE library do not support
-* POSIX named character classes (e.g. [[:alnum:]]).
-*
-* This is a helper function which can be used to convert a regexp
-* which contains POSIX named character classes to one that doesn't.
-*
-* All instances of strings like '[:<class>:]' are replaced by the equivalent
-* enumerated character class.
-*
-* Implementation Notes:
-*
-* Currently we use hard-coded values which are valid only for
-* ISO-8859-1. Also, currently on the classes [:alpha:], [:alnum:],
-* [:upper:] and [:lower:] are implemented. (The missing classes:
-* [:blank:], [:cntrl:], [:digit:], [:graph:], [:print:], [:punct:],
-* [:space:], and [:xdigit:] could easily be added if needed.)
-*
-* This is a hack. I tried to generate these classes automatically
-* using ereg(), but discovered that in my PHP, at least, ereg() is
-* slightly broken w.r.t. POSIX character classes. (It includes
-* "\xaa" and "\xba" in [:alpha:].)
-*
-* So for now, this will do. --Jeff <dairiki@...> 14 Mar, 2001
