Compiled with 64 Bit support the test program doesn't bring an error.

I have now tried to compile PostgreSQL as a 64 Bit binary on Mac OS X
but wasn't able to do so. I'm running against the wall with my
attempts but I must admit that I'm not an expert on that low level C
stuff.

I tried with setting the CFLAGS env variable to '-mpowerpc64 -
mcpu=970 -m64' but with that, I'm not able to compile PostgreSQL on
my G5.

Has someone hints for that?
