My mistake. It was picking up old Qt libraries I had in /Developer/ 
Tools. Removing those and giving a gratuitous -platform macx-g++-64 to  
configure got Qt 4.5 to build for me.

Next up was libmad which failed because its configure doesn't check  
for 64 bit environments. I added a --build x86_64 and it built.

On to myth itself. Snow Leopard defaults to gcc 4.2 which doesn't know  
about -Wno-long-double so I had to comment that out of settings.pro.  
Now it's crapping out in h264.c with a bunch of "suffix or operands  
invalid for `add'" errors on lines 5431, 5443, 7265 & 7277. There were  
also a ton of assembler warnings in libswscale but I looked the other  
way.

Nigel, are you interested in getting the build working on Snow Leopard  
at this time? There's a #warning in qglobal.h that causes "Support for  
this version of Mac OS X is still preliminary" to show on every single  
gcc run. Maybe they're trying to tell us something.
