Since the differences are generally deliberate, what's actually wanted is 
a macro that preserves them.  The basic information of which targets 
support DFP by default / at all and what the default format is on each 
target should be in a single place.  The information about whether $target 
or $host is relevant, and about what the configuration variables should be 
set to if DFP is disabled, should be passed as arguments to the macro.
