-Subject: [PATCH] Append CFLAGS and LDFLAGS to their Config.pm counterparts in
- EU::CBuilder
-
-Since ExtUtils::CBuilder 0.27_04 (bleadperl commit 06e8058f27e4),
-CFLAGS and LDFLAGS from the environment have overridden the Config.pm
-ccflags and ldflags settings. This can cause binary incompatibilities
-between the core Perl and extensions built with EU::CBuilder.
-
-Append to the Config.pm values rather than overriding them.

+Subject: remove duplicate environment variables from environ
+
+If we see duplicate environment variables while iterating over
+environ[]:
+
+a) make sure we use the same value in %ENV that getenv() returns.
+
+Previously on a duplicate, %ENV would have the last entry for the name
+from environ[], but a typical getenv() would return the first entry.
+
+Rather than assuming all getenv() implementations return the first entry
+explicitly call getenv() to ensure they agree.
+
+b) remove duplicate entries from environ
+
+Previously if there was a duplicate definition for a name in environ[]
+setting that name in %ENV could result in an unsafe value being passed
+to a child process, so ensure environ[] has no duplicates.

+#!/usr/bin/perl
+##
+## Name:
+## patchprov
+##
+## Description:
+## Patch the provides list in the perl package PKGBUILD. Scan the appropriate
+## directories under the perl source tree for directories containing dists
+## similar to CPAN dists. Search the files in the distributions for VERSION
+## strings, which are perl expressions. Filters these version strings through
+## the perl interpreter, then transform the dist. names and versions into
+## package names and versions. Finally, we cut out the "provides" array from the
+## PKGBUILD and replace it with the newer version.
+##
+## Usage:
+## patchprov [path to perl source tree] [path to PKGBUILD]
+##
+## Caveats:
+## The path code is not platform independent and will only work in POSIX.
+##
+## Changelog:
+## 06/10/14 JD Rewrite from scratch for perl 5.20.0 and ArchLinux.
+##
+## Authors:
+## Justin "juster" Davis <jrcd83@gmail.com>
