[Gm2] status of gm2 on gcc-5.2.0

[Gaius Mulley]

Hello,

just a short update to say that gm2 on gcc-5.2.0 now passes all but 6
regression tests (including third party non free tests collected over
the years) on x86_64.  It is also working very well on the arm platform
(64 bit).

I could generate a release at present - but have a little tidying up I'd
like to perform and I'd like to investigate line number accuracy in the
debug info.  Anyhow it is probably worth testing on your favourite m2
applications!

regards,
Gaius
