Fedora Update Notification
FEDORA-2020-b11cf352bd
2020-07-09 01:05:44.962939
--------------------------------------------------------------------------------

Name : mingw-pcre2
Product : Fedora 31
Version : 10.33
Release : 3.fc31
URL :   http://www.pcre.org/
Summary : MinGW Windows pcre2 library
Description :
Cross compiled Perl-compatible regular expression library for use with mingw32.

PCRE has its own native API, but a set of "wrapper" functions that are based on
the POSIX API are also supplied in the library libpcreposix. Note that this
just provides a POSIX calling interface to PCRE: the regular expressions
themselves still follow Perl syntax and semantics. The header file
for the POSIX-style functions is called pcreposix.h.
