 Replying to [comment:27 darylew@…]:
 > I've been doing other stuff for several weeks.  When I updated my copy
 of `gcc46`, it also automatically tried to update my copy of `gcc47`.  It
 used my Apple GCC 4.0.1 system compiler, and ended with the same error
 that GCC 4.6 does (can't link in several functions from the C++ runtime
 library).  I'll try redoing it with Apple GCC 4.2 and see if it solves it
 like for `gcc46`.

 I built GCC 4.7 with:

 {{{
 sudo port install gcc47 configure.compiler=apple-gcc-4.2
 }}}

 (It seems to ignore the compiler override if I use "upgrade" instead of
 "install".)  The newly built `gcc47` did compile my test programs,
 although with the same warnings as before some change broke everything:

 A source of concern is that MacPorts' versions of ISL and CLooG are older
 than what GCC 4.7 wants (0.07 and 0.16.3 instead of 0.10 and 0.17.0,
 respectively).  That could be the cause of the whole mess, since I suspect
 the problem is on our end.  (When I tried building GCC 4.7 from GNU's
 archives, it seemed OK, although I never fully installed it.)
