Solaris does not have "fat" binaries (a single binary file that combines 
binaries
compiled for two or more architectures), so it ends up having totally separate
copies, with a way (typically isaexec) to have a single program decide which
to actually execute.

However, OpenSolaris does have "fat" (multi-variant) packages ;)

However, those are not used for 32-bit vs. 64-bit, but for SPARC vs. i386.
