* .topmsg: Remove list of patches.

This is not going to stay current anyway.

Hack in support for requesting heap memory with alignment requirements.

This has not been tested very much.

This reverts commit 6d024607533390d446fff4e0e71fdf7dd17da129.

This is now properly detected automatically.
gcc/testsuite/
	* go.test/go-test.exp: Disable sigchld.go test.
	* libgo/runtime/thread.c (runtime_minit): No alternate signal
	stack on GNU Hurd.

<http://www.gnu.org/software/hurd/open_issues/libpthread_set_stack_size.html>
	* libgo/runtime/go-signal.c (runtime_setsig) [__GNU__]: Don't set
	SA_ONSTACK.

Bug in Hurd's glibc?  The standard says about SA_ONSTACK: If set *and an
alternate signal stack has been declared with sigaltstack()*, the signal shall
be delivered to the calling process on that stack.  Otherwise, the signal shall
be delivered on the current stack.
Revert "gcc/testsuite/"

This reverts commit 2eb51eab5f58fbd110aae626d3239789440ddb94.

The test runs fine if an alternate signal stack is not set (which is known to
be broken).
