I just realized I posted the patch in the wrong list.

Subject: [PATCH] pedantic warning behavior when casting void* to
ptr-to-func, 4.8 and 4.9
To: gcc Mailing List <gcc@gcc.gnu.org>
Hi,
I observed two different behaviors in gcc 4.8.2 and 4.9 regarding
the same issue, IMO both erroneous.
Regarding 4.8.2, #pragma GCC diagnostic ignored "-pedantic" doesn't
work in cases such as:
void* p = 0;
#pragma GCC diagnostic ignored "-pedantic"
F* f2 = reinterpret_cast<F*>(p);
(see testcase in the patch).
The attached patch attempts to fix this issue. Since I no longer have
write access, please
apply this for me if correct (is the 4.8 branch still alive for adding fixes?).
Regarding 4.9, gcc fails to complain at all when -pedantic is passed,
even specifying -std=c++03.
Please let me know if this is truly a bug, in which case I could also
fix it for the latest version as well
(if so, please let me know if I should look into trunk or any other branch).
Thanks,
Daniel.

ping for maintainer.
Could this be considered for 4.8.3 please?
Thanks,
Daniel.

Sorry, ping for maintainer.
We'd do need this for 4.8.3.

It seems some tests didn't run when I tested the patch, sorry about that.
I'll try to run all the tests and update them as needed.
I will post the new patch as soon as possible.
Sorry for the inconveniences.
Daniel.
