[Qemu-devel] [PATCH 5/5] coroutine-sigaltstack.c: Use stack_t, not struct sigaltstack

[Kevin Wolf <kwolf@redhat.com>]

From: Peter Maydell <peter.maydell@linaro.org>

Use the POSIX-specified stack_t type as the argument to sigaltstack()
rather than the legacy struct sigaltstack. This allows us to compile
on MacOSX with --with-coroutine=sigaltstack.
