Subject: [Bug c++/40614] no -Werror= for attribute warn_unused_result
Date: Thu, 02 Jul 2009 23:41:00 -0000 [thread overview]
Message-ID: <20090702234122.27713.qmail@sourceware.org> (raw)

------- Comment #2 from manu at gcc dot gnu dot org 2009-07-02 23:41 -------
We can add an option Wunused-result that controls the warnings.
Wno-unused-result and -Werror=unused-result will then work as expected.
