Synopsis: sigaltstack is missing in libc_r

State-Changed-When: Mon Feb 2 16:07:13 PST 2004
State-Changed-Why: 
libc_r is not going to have sigaltstack().  It was modeled
after the '96 POSIX spec which said that use of sigaltstack()
in a threaded application was undefined.  The 200x POSIX
spec allows sigaltstack() for threads mapped to kernel
schedulable entities and libpthread provides this.  libc_r
is being deprecated in favor of libpthread, so if you want
sigaltstack(), use libpthread.
