I have patched libgo to the weekly.2012-02-07 release. As usual this
message only contains changes to files specific to gccgo. Bootstrapped
and ran Go testsuite on x86_64-unknown-linux-gnu. Committed to
mainline.

This patch to the Go testsuite driver does two things. 1) Disables
stack.go on systems which do not support -fsplit-stack. This test uses
a great deal of stack space and can overrun a thread stack. 2) Builds
select5-out.go without optimization. The test is a generated file that
takes a long tim

Yes, this is ok. I'm sorry for deferring too many 4.6 backports for way too
long, will get to it eventually.

Hi,
the Ada run time depends on DEC-Ada messages, which requires either the native
message compiler or the DEC-Ada library.
Both were not convenient to build a cross-compiler.
This patch removes the dependency simply by using the message code instead.
Tested by building for ia64-hp-openvms.
