+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.
