Comment:

 > Actually, gcc developers are blocked by insufficient support on the host
 because OS X's dyld doesn't support this at runtime.

 Really? Oops, then I just completed an impossible thing :-)

 My opinion is that the above statement about OS X not supporting init
 priorities is a thing of the past, as long as programs compiled with
 native clang support it without problems, proper support should already be
 present since the move to llvm/clang.

 To prove this I patched '''gcc/config/darwin.h''' and changed
 {{{
 #define SUPPORTS_INIT_PRIORITY 1
 }}}

 Then I successfully built the stock 4.7.2 using clang:
 {{{
 export CC=clang
 export CXX-clang++
 ./configure ...
 make
 ...
 }}}

 Could you update the existing Portfile to apply this simple patch and to
 use clang/clang++ during build? (it might not be necessary to explicitly
 use clang, I don't know now, but I can find out in about one hour)
