There is apparently a bug in gcc-4.0 which is being triggered by sdl  
on x86_64. The bug is fixed in gcc-4.2. This is fine on 10.6 since  
gcc-4.2 is the default, but if you want it to work on 10.5/x86_64 you  
need to explicitly SetCC: gcc-4.2. The complication is that gcc-4.2 is  
only available starting with, I think, Xcode 3.1 and early versions of  
10.5 came with Xcode 3.0. If someone never updated their Xcode, they  
wouldn't have gcc-4.2. Since 10.5/x86_64 isn't really officially  
supported by Fink, I'd say BuildDepend: (%m = x86_64) gcc4.2 and then  
have
if [ "%m" == "x86_64" ]; then
   export CC=gcc-4.2
fi
in CompileScript. If someone really wants to run 10.5/x86_64 they'll  
have to make sure their Xcode is up to date.
