Yes.  There are some warnings about target CPU, gnat's use of
gcc 2.8.1 with limited embedded ELF target support versus non-Ada
users going with gcc 2.95 or newer.

Each Ada task is a POSIX thread just like under UNIX.

There are a few nice things you should be aware of.  

  + Non-Ada tasks may call Ada subprograms that use the Ada tasking 
    features.  
  + Ada tasks should be able to use any OS services.
  + There are some bindings for the Classic API if you are interested
    and willing to doublecheck that they actually are current. :)
  + Florist needs to be ported but this should be minimal effort.
