- Subject: [build, doc] Obsolete Solaris 8 support
Continuing to support Solaris 8 is starting to cause lots of trouble:
* Regular support has ended in March 2009, and even extended support
with special arrangements will end in March 2012.
* Access to Solaris 8 patches is restricted to customers with such
arrangements, which I'm not.
* While I can test Solaris 8/SPARC in a Solaris 8 Branded Zone running
on Solaris 10, this testing is limited since only the non-default
alternate thread library is supported there. I could test on bare
metal if need be, but this will likely go away.
* Solaris 8/x86 testing is even worse: running it inside VirtualBox is
dog slow and unreliable and Xen doesn't work at all. I've finally
been able to get myself a machine old enough to still run it or hack
newer machines into running it, but I doubt all this trouble is worth
it.
Therefore I'll soon commit this patch to obsolete Solaris 8 support in
4.7. It will be removed in 4.8 then.
Tested by configuring with --with-target i386-pc-solaris2.8 and noting
the build fail in the gcc subdir, while it continues to work with
--enable-obsolete.
