VOLATILE problem

[Igor Schein <igor@txc.com>]

Hi,

I've made a practice of downloading a gcc-2.96 development snapshot
weekly and compile PARI with it.  About a month ago it started
complainig about VOLATILE void type for function err().  I  posted
about it on their mailing list, but, as in 90% times before, have been
ignored.  So in case this is a compiler feature and not a bug, and
it'll making it into the official gcc release, I wanted to clarify,
what does VOLATILE void type mean, why we need it and can we do away
without it? 

Thanks

Igor
