Yes -- just compile your program on 1.6.  You will quite likely
find it "just works".  Problems to watch out for include:

1. new kernel functionality: if your program relies on post-1.6
   kernel functionality you'll lose;

2. new library routines

   There may not be any of these.  If there are, they may be small,
   and you can add them to the code you're compiling.

It might help if you said what you're trying to build, hint hint. :-)
