pcre bug fix release

Updated pcre packages that fix four bugs are now available for Red Hat
Enterprise Linux 6.

The pcre packages provide the Perl-compatible regular expression (PCRE) library.

This update fixes the following bugs:

* Prior to this update, matching patterns with repeated forward reference failed
to match if the first character was not repeated at the start of the matching
text. This update modifies the matching algorithm not to expect the first
character again. Now, patterns with repeated forward references match as
expected. (BZ#756105)

* Prior to this update, case-less patterns in UTF-8 mode did not match
characters at the end of input text with encoding length that was shorter than
the encoding length of character in the pattern, for example "/ⱥ/8i".This update
modifies the pcre library to count the length of matched characters correctly.
Now, case-less patterns match characters with different encoding length
correctly even at the end of an input string. (BZ#759475)

* Prior to this update, manual pages for the pcre library contained misprints.
This update modifies the manual pages. (BZ#799003)

* Prior to this update, applications that were compiled with the libpcrecpp
library from the pcre version 6 could not been executed against libpcrecpp
library from the pcre version 7 because the application binary interface (ABI)
was mismatched. This update adds the compat RE::Init() function for the pcre
version 6 to the pcre version 7 libpcrecpp library. Applications that were
compiled on Red Hat Enterprise Linux 5 and use the RE::Init function can now be
executed on Red Hat Enterprise Linux 6. (BZ#842000)

All users of pcre are advised to upgrade to these updated packages, which fix
these bugs.

Before applying this update, make sure all previously-released errata relevant
to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red
Hat Network to apply this update are available at
