Subject: coroutine-sigaltstack.c: Use stack_t, not struct sigaltstack
X-Git-Tag: qemu-xen-4.3.0-rc1~17^2~4^2
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=2ad2210a7d2483c4c98423ebd59fad87c6124096;p=qemu-upstream-4.3-testing.git

coroutine-sigaltstack.c: Use stack_t, not struct sigaltstack

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.
