I have attached the ~/tmp/gcc46/gcc/config.log file. As for understanding…

Looks like the checker program ( "confdefs.h") did not have an uptodate idea of w the x86_64 architecture should have or not have, but I may be quite wrong.
While there are other 'failed' "confdefs.h" program examples in this config.log, even an amateur like me was unsurprised by:
"conftest.c:11:28: fatal error: ac_nonexistent.h: No such file or directory"
I mean, who would have thought ac_nonexistent.h would have no file or directory?
(That's another of my poor attempts at a joke), and I do appreciate your help and patience!
