[arch-dev-public] CFLAGS changes with gcc-4.9

[Allan McRae]

Hi all,

gcc-4.9 is due to be released on the 22nd.  This brings a new stack
protection flag, -fstack-protector-strong.  See this blog post for some
details [1].

I would like to do two things with the release of gcc-4.9:
1) Add -fstack-protector-strong to our CFLAGS
2) Rebuild all [core] packages

The rebuild would not only add the extra stack protection, but also
ensure all [core] packages have .MTREE files (which become more useful
with the next pacman release, although still do not test checksums).

Any opinions on both of these points?

Cheers,
Allan
