Hi,
I was going to update ZSNES to explicitly requires pulseaudio-libs
(BZ #1926) and I found out that ZSNES doesn't compile with gcc 4.6.0
(F15+).
The buildlog is here (for devel):
http://buildsys.rpmfusion.org/logs/fedora-development-rpmfusion_free/1018...
The problem seems to be that _FORTIFY_SOURCE breaks parsegen:
https://bugs.launchpad.net/ubuntu/+source/zsnes/+bug/819774/comments/8
Ubuntu *fixed* this disabling _FORTIFY_SOURCE for parsegen. This is
not permitted in Fedora. Unluckily I don't have the necessary
knowledge to fix this myself.
Any help is appreciated.
Thanks,
Andrea.

Hmm, the problem is some auto-generated code, making this not easy and the
error is rather obscure too.
Attached is what I believe is an elegant solution, which only disables
FORTIFY_SOURCE for the auto-generated files. I believe it is even
suitable for sending upstream.

The error CLAIMS that the problem is that fprintf is being called indirectly
through some function pointer. However, I don't see parsegen.cpp generate
any code which would do that. I searched for "fprintf" and I found only
direct function calls.
It might be some GCC optimization making the calls indirect. (Try -fno-
function-cse maybe?)

From what I can gather, parsegen is choking upon
"-Wp,-D_FORTIFY_SOURCE" being passed as argument to it.
At least separating the call to the compiler from parsegen's code
generation seems to fix the issue.
c.f. patch below.
This lets parsegen generate *.h+*.c's and causes the *.c's to be
compiled by "normal compilation rules", instead of trying to compile
them "on the fly" through "parsegen".

I'm very late but I'm updating zsnes to use your patch instead of the
one made by Hans because it has the advantage to use standard Fedora
CFLAGS an no workarounds.
Thanks!
Andrea.
