Hi,

Here is a little patch to fix signal handling under Haiku.

I was using the default calling convention instead of cdecl one for sigaltstack. Obviously, it does not work well when a signal is received. I was also using wrong size for sigset_t.

Now, the tstack test case pass.

The patch is available here :
