Comment (by kencu):

 using gcc7 works perfectly, however:
 {{{
 $ gcc-mp-7 -fstack-protector  -o hello1 hello.c
 $ ./hello1
 Hello, world!
 }}}

 and in detail:
 {{{
 $ gcc-mp-7 -Wl,-v -fstack-protector  -o hello1 hello.c
 collect2 version 7.5.0

         /opt/local/lib/gcc7/gcc/i386-apple-darwin8/7.5.0

 }}}

 so what we have here then is there is apparently nothing wrong with gcc7,
 or apple-gcc42, regarding the configuration or linkages, but it looks at
 the moment like {{{apple-gcc42}}} has either not built or not included the
 {{{libssp*}}} libraries when building on Tiger.

 This is no surprise, really. They were probably just forgotten. If you
 read through the build_gcc script on the {{{apple-gcc42}}} port they do a
 lot of monkeying around with libraries to make them fat, and I think they
 just plainly forgot to put them in (or left them out on purpose).
