Not very. Most of it was having different compiler flags and libs in the 
Makefiles. AIX was very forgiving about null references and a few other 
things that Linux was picky about so there was a burst of bug fixes that 
improved the code. 

IPC was done with ONC-RPC so there was no problem with AIX daemons and 
Linux clients. Eventually that led to some inefficiency. RS6000 is big 
endian and the ONC-RPC XDR encoding is big endian across the network. The 
Linux boxes would swap the order when decoding the XDR. When clients 
switched to cheaper x86 boxes the data was still big-endian encoded on the 
little-endian machines, shipped across the network, and decoded back to 
little-endian.

The MKS Nutcracker tools and runtime was used on Windows boxes so that was 
another set of entries in the Makefiles to build the Windows executables. 
Again there weren't a lot of changes.
