/** 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@dairiki.org> 14 Mar, 2001
