Subject: [PATCH] Explicitly disable `_FORTIFY_FORCE` for `fuzz-decode.c`
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Explicitly disable `_FORTIFY_FORCE` in `fuzz-decode.c`, to fix build
failures with optimizations enabled. The file disables optimizations
halfway through, so we need to ensure that the standard library headers
are included with fortification disabled.
Fixes #91
Thanks to @thesamesam and @amonakov for help.
