I figured that everyone with multiple development environments made
sure their intermediate files were separated.

I use a single source directory for IBO. All my project files are
setup to direct the temporary files (.obj, .dcu) out to a temporary
directory specific to the particular environment; d:\temp\c4 and
d:\temp\d5 etc.

If you do not do this, you are bound to upset the incremental linking,
probably even between two Delphi versions. And if you dont upset the
linking, you are definitely forcing unnecessary unit rebuilds when
switching between environments.
