No, you looked in the wrong config.log

As Ian said, you need to look for config.log in the directory where
configure is being run, that is NOT necessarily the directory where
YOU ran configure.  When you run the top-level configure it
recursively runs configure scripts in sub-directories.  One of those
failed.

In your case it says there is an error in /Users/bhoglund/tmp/gcc46/gcc:

checking size of long long... configure: error: in
`/Users/bhoglund/tmp/gcc46/gcc':
configure: error: cannot compute sizeof (long long)
See `config.log' for more details.

So that's the directory where you need to look in config.log, which as
Ian said is gcc/config.log

Look in there, you will find the "cannot compute sizeof (long long)"
error, with more details.
