Comment # 3 on bug 991027 from Antoine Belvire

Rosenauer has committed its own changes (only add
"-fno-delete-null-pointer-checks" and no -fno-lifetime-dse" and
"-fno-schedule-insns2").

That breaks my repo, I hope it's sufficient to fix the problem (I don't use
Seamonkey myself). Check mozilla:Factory repo when it's finished to build
(https://build.opensuse.org/package/show/mozilla:Factory/seamonkey).

Thanks for your feedback anyway.
