gpc34 fails to build on OS X 10.5.6 PPC -- because of 'sigalstack' declaration errors?

[nosaj.levy@…]

A full log from a clean build is attached. The first bunch of errors are:

/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_lang_gpc34/work/gcc-3.4.3/gcc/config/rs6000/host-darwin.c:38: warning: 'struct sigaltstack' declared inside parameter list

This looks like the kind of thing mentioned in ticket #13191.
