The linker is trying to produce a 32-bit executable, it appears.  In 
lib/crypto/aes/Makefile, the rules for building aes-gen should use 
$(CC_LINK) instead of $(CC).

One other hiccup you might run into is the handling of getsockname 
arguments.  We've had some discussion about fixing it, but for now, the 
code may not work on 64-bit Solaris.  One configuration we do test 
builds on nightly uses:

   CC="cc -xarch=v9 -D_XOPEN_SOURCE=500 -D__EXTENSIONS__"

and seems to work pretty well.  If you've got the Sun compiler (we're 
using Forte Developer 7), you might want to try it.  I'd also be 
interested in how it works with gcc.
