regress and -m64

[Jack Howarth]

Bradley,
    Something still is as astray with your build configuration.
Look at my last set of results.

http://gcc.gnu.org/ml/gcc-testresults/2006-08/msg01333.html

I only have 28 unexpected failures for g++ at -m64 and you
have 1350. Likewise for libstdc++ at -m64, I only have 6 
unexpected failure whereas you have 1668. Try building
some of the g++ testcases manually and see what the errors
are. Assuming you really have the ld64 from Xcode 2.3 installed
I am guessing you have some bogus copies of libstdc++ laying
around in your path.
