Actually it works fine with '-fwritable-strings'. But then you lose

Hi Peter,
The question you ask can be answered trivially - yes, it is definitely a
good idea, please make such a patch. But what is far from being trivial is
the magic reg. expression that is capable of catching all "globals

You get a compiler warning for un-init'd __initdata
