-This package supports working with patch files using quilt.
-
-To regenerate the quilt series file run:
-./gen-quilt-series.sh
-
-Setup environment:
-export QUILT_PATCHES=$PWD
-
-Setup the source:
-./quilt-patch.sh [-f]
-
-Use `-f` if you want to have quilt-patch always remove the existing
-source directory before starting. Otherwise you'll be patching on top of
-an already patched tree generated perhaps by `*pkg prep`.
-
-To add a new patch:
-
-Option 1: Create a new patch:
-
-cd flex-2.6.1/
-quilt new flex-rh1439367.patch
-quilt add tests/test-bison-yylloc/parser.y
-# edit tests/test-bison-yylloc/parser.y
-# you may add and edit several files in the same fashion
-
-Option 2: Add an already prepared patch (e.g. from an upstream commit):
-
-cd flex-2.6.1/
-quilt import -P flex-rh1439367.patch ~/backport/obsolete-bison.patch
-quilt push # if this fails, manually deal with conflicts (as in Option 1)
-
-Finally:
-quilt refresh -p ab
-cd ..
-git add flex-rh1439367.patch
-# edit flex.spec to build with the new patch
-git add flex.spec
-git commit
-
-You're done!

-This patch fixes a flex-2.6.4 build failure on x86_64 and possibly other
-architectures where `size_t' is larger than `int'. The failure occurs as
-follows:
-
-A missing `reallocarray' prototype during compilation means that the
-compiler assumes an `int' return type. When compiling with `-pie' (standard
-for Fedora), addresses on the heap can be larger than `int' can store. Thus,
-pointers returned from `reallocarray' are truncated and any read/write to
-them leads to a SIGSEGV.

-Subject: [PATCH] build: AC_USE_SYSTEM_EXTENSIONS in configure.ac.
-
-This would, e.g. define _GNU_SOURCE in config.h, enabling the
-reallocarray() prototype in glibc 2.26+ on Linux systems with that
-version of glibc.

-Fixes #241.
